chrisfu 3c2a2d23a1 feat(mariadb): add temporary external storage support for Merlin
- Enable mounting borrowed USB disk (exFAT) persistently at `/external`.
- Migrate MariaDB datadir to `/external/mariadb` with bind mount at `/srv/mariadb/mariadb`.
- Add migration marker and rollback support to prevent accidental remigration.
- Include Ansible tasks for external storage setup and migration validation.
