Fix week navigation using ref to eliminate stale closure entirely

Previous wsArg approach still suffered from useCallback memoisation
interacting with React batching — loadAll could fire with the render-
before-last week start. Switch to weekStartRef (written before every
loadAll call and on every render) so loadAll always reads the live
value regardless of when the memoised function was created.

Also removes unused putWarningThresholds import (added externally).
