Fix bookstack deployment to use existing resources

- Change MySQL from StatefulSet to Deployment to match existing setup
- Use existing PVC mysql-data-encrypted (contains live data) instead of creating new mysql-data
- Add PersistentVolumeClaim for bookstack-config to persist APP_KEY and configuration
- Remove duplicate MySQL resource definitions
- Align with current working deployment while making Forgejo the source of truth
