Mirror the Withings integration actions on the WHOOP card. A new
POST /api/integrations/whoop/test runs a live, rate-limited probe
against the WHOOP basic-profile endpoint, refreshing the token via
getValidToken and classifying HTTP/transport failures into the same
errorCode taxonomy the Withings test route uses. A new
POST /api/integrations/whoop/resume clears a parked integration via
resumeIntegrationFromPark for the whoop provider.
The settings WhoopCard gains the shared Test-connection button, the
parked-state resume banner, and switches the full-sync icon to
RefreshCw for visual parity. Sync-now and sync-all are unchanged.
