fix(immich): size postgres probes for HDD stalls

Postmaster was SIGKILLed in a loop: 70s fsync stalls on the loaded rotational disk outlasted the 5-minute startup budget and the 60s liveness tolerance, and every kill bought another full WAL replay. Startup budget 15min, liveness 5x60s. Already applied live with kubectl; this keeps git in sync.
