prometheus: increase memory to 4Gi and probe delays for TSDB compaction

Browse source 
Compaction of 5 years of TSDB blocks was OOM-killing at 3Gi (18 restarts
in 8h), causing sustained IO pressure on the PVE host spinning disk.
Increase liveness probe delay to 300s so WAL replay completes before
the probe kills the pod.
