kubectl apply computes a 3-way merge. The base PVC has no storageClassName
(nil), but the already-bound PVC in the cluster has storageClassName=local-path.
This diff caused apply to attempt a mutation on a bound PVC — forbidden by k8s.
Fix: patch the PVC with storageClassName=local-path so desired state matches
live state and apply produces no diff on the PVC.

The mysql-data-pvc was already dynamically provisioned by the cluster's
'local-path' StorageClass. The overlay patch tried to change storageClassName
to 'manual' and volumeName on an already-bound PVC, which Kubernetes forbids:
"spec is immutable after creation except resources.requests"
Fixes:
- Remove mysql-pvc-patch from kustomization.yaml (PVC left as-is)
- Remove mysql-pv.yaml resource (not needed with dynamic provisioner)
- Add comment explaining when manual PV/PVC is needed vs not
Jenkinsfile: add --timeout and FQDN to smoke test curl; add comments
explaining MySQL Recreate strategy startup timing expectations.
