Janis	5619c8223a	fix: resolve 6 coordinator bugs (cache eviction, rebalance race, pod matching, lookup inefficiency) - Add lastUpdatedMs timestamp to GameCacheDto to track actual game updates instead of heartbeat time. Fix cache eviction incorrectly marking correspondence games as idle. - Use atomic SPOP in LoadBalancer.getGamesToMove() to prevent concurrent rebalance calls from selecting same games for migration. - Add game→instance reverse mapping (nowchess:game:$gameId:instance) to eliminate O(instances) linear scan during cache eviction. - Fix HealthMonitor pod matching from loose contains() to reliable endsWith() to prevent matching unintended pods with similar names. - Update FailoverService to maintain game→instance mappings when migrating games during failover. - Update CacheEvictionManager to use game→instance mapping for O(1) lookup instead of O(n) instance scan.

Janis	2d76c001fe	fix: refresh Redis TTL on instance heartbeat to prevent false DEAD marking Instances were being incorrectly marked DEAD because their Redis key TTL was not being refreshed on heartbeat. HealthMonitor.checkRedisHeartbeat() checks pttl > 0, which fails when the TTL expires even if the instance is alive and sending regular heartbeats. Now pexpire(key, heartbeatTtl) is called on each heartbeat to keep the key alive. Prevents scaling messages from undercounting healthy instances.
