fix(monitoring): Loki uses Recreate strategy for RWO PVC rollouts (DEV-483)

Browse source 
RollingUpdate deadlocks the Loki rollout because loki-storage-encrypted
is a Hetzner CSI RWO volume — the new pod on worker-2 cannot attach the
PVC while the old pod on worker-1 still holds it. Recreate drains the
old pod first so the CSI detaches the volume cleanly.

Same pattern as the Harbor fix (commit 56e598f).
