✨(rooms) soft delete rooms from internal and external API

Before this commit:
1. Rooms could be hard-deleted from the internal API (unused by the
   frontend).
2. The external API had no way to delete a room.
3. The admin could hard-delete rooms.

What this commit does:
1. Add a `deleted_at` field to Room. `Room.objects` hides soft-deleted
   rooms; `all_objects` stays the default manager so deleted rooms keep
   reserving their slug and PIN code.
2. Soft delete rooms from the internal API (replacing hard delete) and
   the external API (new DELETE, owner only, `rooms:delete` scope). The
   LiveKit room is closed and its participants disconnected; if closing
   fails, the soft delete is rolled back and an error is returned.
3. Answer 410 Gone on detail operations on a deleted room (after
   permission checks). Its can still be read but not modified.
4. Close LiveKit rooms recreated after deletion by participants still
   holding a valid token (room_started webhook).
5. Frontend: participants in the call land on the feedback page without
   the rejoin button, lobby participants see a "meeting deleted" screen,
   and opening the link shows an error instead of recreating the room.

Untouched by this commit:
- The admin still hard-deletes rooms, without closing the LiveKit room,
  and lists soft-deleted rooms alongside active ones.
- Purging soft-deleted rooms (hard deletion) is not handled.
- Scheduled deletion is not handled.

 ## [Unreleased]
 
+### Purging deleted rooms

+Deleting a room now only soft deletes it: it is hidden but keeps its slug and PIN code. The `purge_inactive_rooms` command also permanently deletes soft-deleted rooms. See [the room purge documentation](docs/features/room-purge.md).
+
+- Inactive soft-deleted rooms are purged along with the other inactive rooms: if `ROOM_INACTIVITY_DELETION_DAYS` is already set, nothing else is needed.
+- The new `ROOM_DELETED_RETENTION_DAYS` setting purges soft-deleted rooms that many days after their deletion, whether they are inactive or not. It is unset by default.
+- As for inactive rooms, a deleted room holding a saved recording its users may still access is kept until that recording expires.
