librelad 34bd6d7936 feat(backup): kopia + borg system-config adapters (engine parity)
Mirror the restic system-config adapters for the other two engines, each in that
engine's own convention, so system backup/restore/status/retention work on any
location regardless of engine:

- kopia: BackupSystemToLocation (--tags system:config), SystemSnapshotsJson
  (filter tag system:config), RestoreSystemLatest, ForgetSystem (per-source policy
  on $configs_dir + maintenance).
- borg: BackupSystemToLocation (archive system-<host>-<ts>, comment system=config;
  no app is named "system" so the namespace can't collide), SystemSnapshotsJson
  (--glob-archives system-<host>-*), RestoreSystemLatest, ForgetSystem (prune the
  system-<host>-* glob).

No dispatcher change needed — engineBackupSystem/SystemSnapshotsJson/
RestoreSystemLatest/ForgetSystem already resolve <engine><fn> per location. All
three engines now define the full set; syntax clean.
