Critical fix: StorageClass mountOptions only apply during dynamic provisioning. Our static PVs (created by Terraform) were missing mount_options, so all NFS mounts defaulted to hard,timeo=600 — the exact stale mount behavior we were trying to eliminate. Adds mount_options directly to the nfs_volume module PV spec and to the monitoring PVs (prometheus, loki, alertmanager). Requires re-applying all stacks to propagate to existing PVs.
