feat(housekeeping): mute-user + kick-user packets

Incoming 9104 HousekeepingMuteUserEvent — (userId, reason, minutes).
Unlike ModToolSanctionMute which takes a fixed-bucket minutes arg
from a CFH context, this one applies an arbitrary in-session mute via
Habbo.mute(seconds, false). Mute is online-only (the live Habbo object
holds the remaining seconds), so an offline target returns ok=false
with `user_offline`. The reason string, if non-empty, is delivered via
Habbo.alert so the muted user sees why.

Incoming 9105 HousekeepingKickUserEvent — (userId, reason). Replicates
the ModToolManager.kick body (leave room + alert) locally so HK doesn't
piggyback on ACC_SUPPORTTOOL the way ModToolManager.kick does — keeps
the permission model `acc_housekeeping`-only. Respects ACC_UNKICKABLE
the same way the legacy path does.

Both reuse HousekeepingActionResultComposer with their own actionKey
(user.mute / user.kick).

`mvn compile` clean.
