Jeremy Daer 94a48aacb6 Guard push-subscription endpoints against SSRF (#265)
* Guard push-subscription endpoints against SSRF

Web push delivery POSTed to the endpoint URL a user supplied when
registering a subscription, with no scheme, host, or private-network
check -- unlike the OpenGraph unfurl path, which already routes through
the shared SSRF address policy (surfguard). Any authenticated user could
register a subscription whose endpoint pointed at an internal address and
have the server fetch it on every chat message: blind SSRF for internal
recon and reachability probing, plus a thread-pool DoS on the delivery
pool.

Validate the endpoint when the subscription is saved: it must be HTTPS,
its host must belong to a known browser push service (allowlist), and it
must resolve to a public IP. On every delivery, re-resolve the host and
pin the connection to that public IP so a later DNS rebind can't redirect
the request to an internal address. If no public IP resolves at delivery
time -- a rebind, or a subscription that predates this validation --
delivery is skipped rather than falling back to re-resolving the raw
host.

Adds model, controller, and delivery-pinning tests, plus a DNS stub
helper for deterministic resolution in tests.

* Route push endpoint guarding through RestrictedHTTP::PrivateNetworkGuard

The endpoint SSRF check already delegated its private-network classification
to surfguard, but called Surfguard.resolve_public_ips directly rather than
through RestrictedHTTP::PrivateNetworkGuard -- the hostname-in, address-out
shim #241 established as the app's single guarded-outbound entry point and
that Opengraph::Fetch resolves through. Route push resolution through the same
guard so once-campfire keeps one place that resolves and classifies outbound
addresses. Behavior is unchanged: the guard raises Violation when a permitted
host resolves only to blocked addresses (previously an empty list -> nil) and
propagates Surfguard::Unresolvable for a host that resolves to nothing; both
map to a nil endpoint IP, which fails validation and skips delivery. The
allowlist, HTTPS/443 constraints, and per-delivery IP pinning are unchanged.

* Address push-SSRF review: defer DNS off enqueue path, disable proxy on pinned path, revalidate on re-registration

- Resolve the guarded endpoint IP lazily inside WebPush::Notification#deliver
  (on the bounded delivery worker) instead of eagerly when the notification is
  built on the serial enqueue path, so a slow resolver can't stall the push job
  before any delivery starts. resolved_endpoint_ip only reads the already-loaded
  endpoint attribute, so it is safe off the AR connection.
- Pin the delivery socket with an explicit nil proxy address so http_proxy/
  https_proxy can't route the request through a proxy that re-resolves the host
  and defeats the ipaddr pin.
- Revalidate an existing subscription on re-registration so a row predating
  endpoint validation gets the same 422 as a fresh create instead of being kept
  alive by touch.
- Regression tests: resolution deferred to delivery, pin survives proxy env,
  legacy invalid row rejected with 422.

* Bound the web-push delivery queue (max_queue, not the ignored queue_size)

Concurrent::ThreadPoolExecutor takes :max_queue; :queue_size was silently
ignored, leaving the delivery backlog unbounded (max_queue: 0). A flood of
valid push subscriptions could accumulate queued deliveries without limit --
more acute now that each delivery task also resolves DNS. Using max_queue: 10000
activates the intended cap; overflow raises RejectedExecutionError under the
default :abort policy, which deliver_later already rescues (push is best-effort,
retried on the next message).

* Trim push-SSRF guard comments to match house style

Apply the review suggestions on the push-subscription SSRF guard: replace
the verbose rationale comments with terse one-liners (or drop them where
the code speaks for itself). No behavior change -- the Surfguard-shim
routing, per-delivery public-IP pin, and bounded delivery queue are
untouched.

Ronald Lokers 3ca1dcbf77 Allow bots to update and destroy their own messages
Bots can only create. A lifecycle notification — an alert that fires and then
resolves, a deploy that starts and finishes, a backup that runs — therefore has
to post a second message, and the room becomes an append-only log of states
rather than a view of the current one.

Adds PATCH and DELETE inside the existing bot_key scope, routed to
Messages::ByBotsController. The body is read the way create reads it, so
updating a message is the same request shape as posting one.

No new authorization: both actions already run through ensure_can_administer,
and can_administer? grants access only to a record the user created, so a bot
key reaches that bot's own messages and no others. set_room narrows it again by
looking the room up through the bot's own memberships. A leaked bot key gains
what it could already do by posting: write to rooms that bot belongs to.

update answers head :ok rather than the redirect, which meant extracting the
update and its broadcast into update_message — calling super and then head
would double render, since the parent redirects inside the action. destroy
needs no split, because the parent renders implicitly like create does.

Stanko K.R. 80c9e7fbfe Adjust to the in-house style
- Use jbuilder instead of hashes
- Use resource instead of direct HTTP verbs
    Verbs only make sense if you have one or two routes, if there are
    multiple that emulate what resource does then it's better to use resource.
- Paginate using link headers
- Cache responses

Jeremy Daer 3b509f55ca Scope the unread rooms stream per user
UnreadRoomsChannel streamed from a hardcoded global name, and every message
published its room id to it. Any authenticated user, including one with no
memberships at all, could subscribe and watch which rooms were active and exactly
when, across every closed room and direct conversation on the account. The browser
filters ids it doesn't recognise, but that happens after delivery.

Its sibling ReadRoomsChannel is already scoped per user; this mirrors it, and
message creation fans the notice out to the room's members instead of broadcasting
it to everyone. No message content was exposed either way, only the timing.

Jeremy Daer 5c5c82b27a Scope room lookup to the type each controller administers
Rooms::DirectsController relaxes ensure_can_administer to true, because every
participant in a direct room may administer it. set_room was inherited unscoped,
though, so that relaxation applied to any room the caller was merely a member of:
DELETE /rooms/directs/<id> destroyed open and closed rooms and all their messages.

The same unscoped lookup let a direct room be loaded by the opens and closeds
controllers, where force_room_type promoted it. Promoting a DM to open grants every
user on the account membership and republishes the whole conversation, including the
other participant's messages; converting it to closed lets the initiator revise who
is in it and lock the other participant out.

Each controller now narrows room_scope to the types it may act on. Opens and closeds
keep reach into each other, since converting between them is a feature. Neither can
reach a direct room, and directs can only reach directs.

Room also refuses to change type away from Rooms::Direct, so the invariant holds for
any future caller of becomes! rather than only these two controllers.

Mike Dalessio b065b40a34 Disable libvips unfuzzed operations (#226)
and add test coverage for (un)supported file types.

The avatar and logo variants move into the models and return nil for content
types that are no longer variable, so the controllers fall back to the initials
avatar and stock logo icon instead of raising `ActiveStorage::InvariableError`.

John-Mason Shackelford 20ab5b1bc6 feat: Add bot API endpoint for adding reactions (boosts) to messages
Adds a new endpoint that allows bots to add emoji reactions (boosts) to messages:
POST /rooms/:room_id/:bot_key/messages/:message_id/boosts

This enables bots to acknowledge messages with reactions like 👀 (eyes) when
mentioned, providing immediate feedback to users before generating a full response.

The endpoint:
- Validates the bot is a member of the room
- Validates the message exists in the room
- Broadcasts the boost to connected clients via Turbo Streams
- Returns 201 Created on success, 404 if room/message not found

John-Mason Shackelford c82a8d38c0 fix: Use correct room messages in pagination tests
Fixed test bug identified by Copilot code review: pagination tests were
using Message.first and Message.last which could return messages from
different rooms than the test's @room (watercooler).

Now explicitly using messages(:fourth) and messages(:thirteenth) which
are fixtures belonging to the watercooler room where bender bot is a member.

John-Mason Shackelford 057d56513e fix: Align create and index to both return 404 for non-member rooms
Both create and index now return HTTP 404 Not Found when a bot tries to
access a room it's not a member of. This is consistent with REST API
security best practices (not revealing resource existence) and ensures
read and write permissions are handled identically.

Changed create action to no longer call super (which rendered HTML) and
instead directly handle the request with proper JSON API error responses.

Added test to verify create returns 404 for non-member rooms.

John-Mason Shackelford 5340f3da01 fix: Ensure bot can only read messages from rooms it is a member of
Added explicit RecordNotFound handling to return 404 when a bot tries to
read messages from a room it's not a member of. This matches the security
model used by the create action.

Added tests to verify:
- Bot gets 404 when trying to read from room it's not a member of
- Bot can successfully read from room it IS a member of

John-Mason Shackelford d4a56784e0 feat: Add bot API endpoint for reading room messages
Adds a new GET endpoint at /rooms/:room_id/:bot_key/messages that allows
bots to read messages from rooms they are members of.

The endpoint returns JSON with:
- Room info (id, name)
- Messages array with body (plain/html), created_at, and creator info
- Pagination info (oldest_id, newest_id, has_more)

Supports pagination via ?before=:id and ?after=:id query parameters,
consistent with the existing pagination in the messages controller.

This enables AI bots and other automated agents to understand conversation
context when responding to messages, rather than only receiving the single
message that triggered the webhook.

Kevin McConnell 30fe6ab121 Add IP-based user banning
This adds the ability to ban a user by their IP address.

When an admin is viewing a user profile, a new "Ban user" button is
present. Clicking on that will:

- Create a ban on the IP addresses that were tracked for that user's
  sessions
- Remove all the messages authored by that user
- Log the user out immediately

In addition, that user will no longer be shown in most user lists in the
app. They are still shown to admins, in account settings. Viewing their
profile from there will now show a "Remove ban" button which can be used
to restore their access (it doesn't restore their messages though --
those are already gone -- it just removes the blocks so they can log in
again).

Jacopo 3d0a10dbdd Security: Fix user impersonation via custom bot token
If bot_key has no right-hand side (ex: 1-), bot_token will be nil, and the query will match a User record if bot_id matches a valid ID.
Fix it relying on `active_bots` instead.
