- Configure consistent domain 'home.lab' for ID mapping across all machines
- Update sleeper-service NFS server with proper security (root_squash, all_squash)
- Create reusable NFS client module (modules/services/nfs-client.nix)
- Deploy NFS client configuration to grey-area and congenital-optimist
- Maintain consistent media group GID (993) across all machines

- Test and verify NFS connectivity and ID mapping functionality
Resolves permission management issues and enables secure file sharing
across the home lab infrastructure.

- Maintain security with root ownership while allowing group collaboration
This resolves NFS permission issues by providing consistent group-based access
control across all media services and storage directories.
