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

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.
