Watch: waiting-count complication and multi-select questions

A WidgetKit extension (accessoryCircular, Rectangular, Inline, Corner) shows
GET /v1/summary. The device token moves to the App Group's Keychain access
group on launch so the extension can read it without re-pairing; the app
reloads the timeline when its feed counts change and on notifications.
Multi-select questions toggle options and send an array of values.
