Reduce task polling frequency and raise rate limits to prevent 429s

Browse source 
With 8+ active tasks, polling every 5s generates ~96 task_status
requests/min, exceeding the 60/60s rate limit. Two fixes:

- Adaptive polling: 30s when WebSocket is connected (safety net),
  5s only when WebSocket is down (primary source)
- Raise task_status rate limit to 200/60s and tasks_for_user to
  60/60s to handle burst scenarios (page reloads, WS reconnects)
