Garmin auth/sync routes move under /api/garmin/*; sync.Service becomes garmin.Sync with garmin.SyncConfig/ClientConfig; applog becomes internal/log; the test mock moves into the garmin package as MockClient (breaking the test-only import cycle the merge created); stale test URLs and type names updated to match.
