fixup! feat: add prune_db command to prune old checkouts, builds and tests. * Delete rows older than a given age with manual cascade (checkout -> builds -> tests) * --origins scoping, --dry-run and a --yes confirmation. Extract parse_interval into a shared helper and add integration tests.

    * Add tables parameter.
    * Protect issue related rows by default, and add parameter to
      bypass.
