Upgrade Nextcloud setup to use compose files

- Integrated MariaDB role into Dockerbox configuration
- Moved proxy role to the end to avoid early endpoint activation
- Temporarily disabled select roles for future re-evaluation
- Introduced flush_handlers task for early MariaDB restart
- Moved a few Nextcloud tasks to handlers
- Configured Nextcloud to utilize the host's MariaDB instance
- Enhanced overall code linting quality
