feat(communication): housekeeping hotel alert + dashboard + audit log

Outgoing 9127-9129: send-hotel-alert (message string), get-dashboard
(no args), list-action-log (limit int).

Incoming 9206 HousekeepingDashboardEvent + 9207 ActionLogEvent with
matching parsers and data classes. Dashboard is a flat one-shot
parse — no count prefix; action log uses the standard "count + N
entries" list pattern.

Closes the HK packet surface — yarn compile:fast clean.
