feat(nixos): auto-start UxPlay as a user systemd service

Run UxPlay under graphical-session.target so the AirPlay receiver is
discoverable as soon as the GNOME session is up, instead of requiring
a manual `uxplay` invocation per login.

Constraint: UxPlay needs the active graphical session for display + PipeWire
Rejected: system-level service | runs before user session, no display/audio access
Rejected: GNOME autostart .desktop entry | no Restart-on-failure semantics
Confidence: high
Scope-risk: narrow
Directive: keep wantedBy on graphical-session.target (not default.target) so
  the unit only runs when a desktop session is live
Not-tested: behavior on fast user switching between two desktop sessions
