feat: caller cache invalidation endpoint + worklist auth fix

- POST /api/caller/invalidate — clears Redis cache for a phone number
- WorklistController: resolves agent name from login cache (avoids currentUser query)
- AuthController: caches agent name in Redis during login (keyed by token suffix)
- WorklistModule: imports AuthModule (forwardRef for circular dep)
