feat(communication): housekeeping ban-user + generic action-result

* HousekeepingBanUserComposer (OutgoingHeader 9102): (userId,
  reason, hours).

* HousekeepingActionResultEvent + Parser (IncomingHeader 9201):
  generic ack carrying (actionKey, ok, actionId, message). Same
  parser will back mute / kick / give-credits / room-close / etc.
  callers — adding a new HK action only needs a new outgoing
  composer plus the right ACTION_KEY constant on the server side.

vitest 138/138, `yarn compile:fast` clean.
