feat(housekeeping): rooms domain — find/search + open/close/mute/kick-all/transfer/delete

Eight new incoming handlers + two new outgoing composers cover the
full rooms-domain HK panel.

* Outgoing 9202 HousekeepingRoomDetailComposer — single room with a
  leading `found` boolean. Writes the IHousekeepingRoom shape via a
  static `appendRoomFields` that HousekeepingRoomListComposer shares.

* Outgoing 9203 HousekeepingRoomListComposer — `count` then N rooms.
  Used for both find-by-name (exact match, up to 50) and the prefix
  autocomplete dropdown (up to 8).

* Incoming 9110 HousekeepingFindRoomByIdEvent — loadRoom(id, false)
  covers both the in-memory cache and the offline `SELECT * FROM rooms`
  path. No `loadData` so HK doesn't pull furni/bots/pets just to
  render a summary.

* Incoming 9111 HousekeepingSearchRoomsEvent — (query, exactMatch,
  limit). Branches between `name = ?` and `name LIKE ?` so the same
  wire packet serves both the autocomplete and the exact-find flows.
  Hard-capped to 50.

* Incoming 9112 HousekeepingRoomStateEvent — (roomId, open). Toggles
  Room.setState(OPEN | LOCKED) and persists via Room.save(). One
  packet covers both the open and close API endpoints.

* Incoming 9113 HousekeepingMuteRoomEvent — (roomId, minutes). Room.
  setMuted is a boolean, so minutes==0 unmutes and minutes>0 mutes.
  A scheduled auto-unmute is left for a future slice; the wire field
  is reserved.

* Incoming 9114 HousekeepingKickAllFromRoomEvent — Room.ejectAll().

* Incoming 9115 HousekeepingTransferRoomOwnershipEvent — UPDATEs both
  rooms.owner_id and rooms.owner_name so the navigator cached name
  doesn't go stale. Validates the new owner exists via
  HabboManager.getHabboInfo before touching the row.

* Incoming 9116 HousekeepingDeleteRoomEvent — ejectAll + dispose +
  uncacheRoom + DELETE FROM rooms, mirroring the minimum-viable
  subset of RequestDeleteRoomEvent. Pets/guild/custom-layout cleanup
  is skipped on this slice (orphans don't crash the emulator).

`mvn compile` clean.
