fix: Wire real data sources across players, analytics, status, and maps services

- players: Primary data from player_sessions (online status, playtime aggregates);
  ban/unban status overlaid from player_actions latest action per steam_id.
  Register PlayerSession entity in PlayersModule. Extend NATS forwarding to
  include 'unban' alongside kick and ban.
- analytics: Fix retention period boundary bug — sessions were queried with only
  a lower-bound filter (MoreThan), causing all future cycles to bleed into earlier
  wipe windows. Replaced with Between(wipeDate, endDate) for correct isolation.
- status: Replace hardcoded player_count=0/max_players=0 with live data from
  most-recent server_stats row per license. Register ServerStats entity in
  StatusModule. Falls back to 0 gracefully when no stats exist yet.
- maps: File buffer was computed and discarded — never written to disk.
  Now writes to /app/map_data/{licenseId}/{timestamp}_{filename} (tenant-isolated,
  docker volume map_data). Creates directories with mkdirSync(recursive:true).
  Logs success/failure via NestJS Logger. Throws 500 on disk write failure
  instead of silently losing data.
