Subject: [PATCH] Fix ESP32-S3 ESP-NOW startup timing

Add an S3-only 10 ms delay before disconnecting Wi-Fi, allowing station and channel setup to complete. The ESP-NOW diagnostic receiver already uses the same settling delay.

This resolves ESP-NOW telemetry reception on the MFD Crossbow ESP32-S3 target. The classic ESP32 target works without the delay and remains unchanged.

Other S3 VRX targets using Vrx_main.cpp may also benefit, although only the MFD Crossbow configuration has been hardware-tested.
