Message content is delivered over turbo streams, which ran on the stock
Turbo::StreamsChannel. That channel verifies the signature on the stream name and
nothing else. The name carries no expiry and no binding to a user, so one read off
the page while a member kept working after the membership was revoked.
Revocation made this worse rather than better. Membership#after_destroy_commit
disconnects the user with reconnect: true, and the client replays its subscriptions
on the new socket: RoomChannel re-checks membership and rejects, while the turbo
subscription re-verified only the signature and was accepted.
RoomMessagesChannel re-checks membership on every subscribe, deriving the room from
the verified stream name so there is no parameter to point elsewhere. Since the
subscriber names the channel it wants, the stock channel would otherwise be a way
around that check, so it now turns these stream names away and this is the only door.
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`.
