feat: add TMP3 support and fix shard probe lifecycle bug

Add Trivia Murder Party 3 (Playtest) ticker and seed data. Bind-mount
tickers.json in docker-compose so ticker changes take effect on restart
without image rebuilds.

Fix shard monitor probe poisoning game lifecycle state — the player-count
probe no longer sets gameFinished, which was preventing the main WS from
processing room/lock and room/exit for games like TMP3 that don't send
entity updates.
