Requesting a WiFi AP scan from the WebUI or [ESP410] triggers the TCP watchdog before the scan completes. This change pauses the request during the async scan and sends the AP list once the results are ready.

Steps to reproduce:

  1. Send [ESP410] through terminal or request an AP scan in the WebUI's FluidNC Settings page by clicking the magnifying glass next to the Sta/SSID field.
  2. TCP watchdog gets triggered after several seconds and FluidNC restarts.
