librelad 21afae2eff refactor(desudo): drop runtime root from docker_run, sqlite guards, restores
- docker_run: in rooted mode run docker AS the manager via the docker
  group (no sudo); the type=='sudo' branch was unreachable dead code
- 8 db helpers: fix 'command -v sudo sqlite3' guard to 'command -v
  sqlite3' (bodies already query via runInstallOp)
- restic/kopia single-file dump: write target_file via runBackupOp tee
  (as the backup user, matching the snapshot-restore path) instead of
  root tee
- adguard auth: root-owned scratch via runSystem mktemp
