Migrate from path-based persistence (/persist/var/lib/*) to dedicated
BTRFS subvolumes for better data isolation and snapshot capabilities.
- Move valuable user-facing services to /srv/* with srv-* subvolumes:
- forgejo: git repositories and database
- opengist: paste data
- minecraft: game world data
- lighttpd: static web content
- containers: OCI container volumes
- Update home directory to use hm-sajenim subvolume on viridian disk
- Remove jupyterhub service (no longer in use)
- Update borgbackup paths to match new service locations
- Follow upstream service defaults where possible for maintainability
Services kept on /persist (disposable state):
- traefik, crowdsec, murmur
Move all allowUnfreePredicate declarations to global configs to prevent
the "last definition wins" merging issue. Unfree packages are now managed
in two central locations:
- NixOS system packages: nixos/common/global/default.nix
- Home Manager packages: home-manager/sajenim/global/default.nix
