Client already renders the siege-map countdown but never received the packets.
New ICastleSiegeStatusViewPlugIn + RemoteView impl send the raw S6 packets:
C1 B2 17 (battle start/stop flag, arms the countdown) and C1 B2 1E (remaining
hour/minute). CastleSiegeEventPlugIn broadcasts them to players on the battle map
every 10s during Siege and sends stop at Settlement. No client changes. +1 test.
