maziggy 4ad43c96de fix(db): configurable connection pool + auth_enabled cache for large farms (#2572) ...

Large PostgreSQL farms exhausted the fixed pool (pool_size=10 +
max_overflow=20): with ~93 printers every connection sat idle in
transaction and unrelated requests waited out the 30s pool timeout or
failed in the auth middleware.

- Make pool sizing env-configurable (DB_POOL_SIZE / DB_MAX_OVERFLOW /
  DB_POOL_TIMEOUT / DB_POOL_RECYCLE); raise the Postgres default to
  20 + 80 with pool_pre_ping + pool_recycle=1800.
- Cache the auth_enabled probe (30s) to drop a per-request DB round-trip.
  Only enabled=True is cached, so staleness fails closed; set_auth_enabled
  invalidates immediately.
- Add GET /api/v1/system/db-pool exposing resolved config + live
  checked_out/checked_in/overflow gauges without consuming a connection.

Session-hygiene (connections held across MQTT/FTP/camera/3MF I/O) is a
separate follow-up.
