fix(k8s): add PV/PVC selectors and set 512Mi storage limit

- Add labels to all PersistentVolumes for proper identification
- Add selectors to all PersistentVolumeClaims to match specific PVs
- Set all storage sizes to 512Mi for conservative resource usage
- This resolves PV binding issues where volumes were binding to wrong PVCs

Affected services: gitea, memos, filestash, uptime-kuma
