feat: Add comprehensive restart policy documentation and Sablier lazy loading support

- Add SERVER_HOSTNAME env var for Sablier group naming
- Update default hostname from 'jarvis' to 'debian' for generic repo compatibility
- Add restart policy documentation to all docker-compose files
- Add Sablier labels to lazy-loaded services (jellyfin, dozzle, glances, code-server, homarr, dokuwiki)
- Update sablier.yml template to use debian- prefixes
- Enhance deploy script to auto-detect hostname and update configurations
- Ensure all YAML files remain syntactically valid
