Fix browser tab crash on print completion (debounced invalidations)

When a print completes, multiple WebSocket messages are sent rapidly
  (print_complete, archive_updated, etc.). Each was immediately invalidating
  the archives query, causing a cascade of rapid re-renders that crashed
  the browser tab.

  Added debounced query invalidation to useWebSocket.ts:
  - Multiple invalidation requests within 100ms are coalesced into one
  - Uses requestAnimationFrame to avoid blocking the main thread
  - Properly cleans up timeouts on unmount
