ksmithandClaude Sonnet 5 766883c992 Add the ability to hide a DM conversation (#52 follow-up)
Neither participant could get rid of a DM at all -- Leave/Delete were
both deliberately hidden for DMs during the initial build to sidestep
an edge case (removing a membership would break find_or_create_dm's
exactly-two-members assumption), but that left no way out whatsoever.

RoomMembership.hidden_at is a per-viewer display flag, not a
membership deletion: hiding a DM only sets it on your own membership
row, so it disappears from just your sidebar without touching the
other participant's copy or any messages. It's automatically cleared
(reappearing) in two cases: a new message arrives in the room
(broadcast_new_message), or find_or_create_dm resolves back to the
same room because either person re-opens it from the People list --
both count as the conversation being active again.

Also fixes two now-flaky tests (test_message_edit, test_reactions):
broadcast_new_message doing more work before returning shifted timing
enough to expose a pre-existing race where a per-user-channel frame
(desktop_notification/unread_update) could legitimately arrive before
a connection's own "joined" ack. Broadened their existing _recv()
noise-filtering helper (already used for member_updated) to cover
those types too, and used it at the two call sites that were reading
raw receive_json() instead.
