📄 Description

Addresses 2.4 GHz Wi-Fi interference and signal dropouts discussed in #198.

OpenPuck's default channel 18 (2418 MHz) sits inside Wi-Fi Channel 1. This PR allows dynamically switching to clean frequencies outside or between Wi-Fi bands (e.g., channels 74–80 or guard channels 26/52).

Noise Survey & Auto-Channel: Measures ambient 2.4 GHz noise (rfMeasureChannelNoise) to sweep and adopt the cleanest candidate channel at boot or when degraded by packet loss.
Seamless Live Hopping: Bursts 8 0xE1 frames on the active channel so connected controllers migrate to the new frequency without dropping connection.
Config Persistence: Saves sessCh and autoChannel to cfg.bin.
WebUSB & WebUI: Protocol v22 status blob reporting, on-demand spectrum survey (opcode 0x18 / frame 0xAD), channel selection UI, and live spectrum bar chart.
Console: Adds C (survey spectrum) and C <1..80> (hop and save).
Tested with make check and make build.

(Authored with LLM assistance, verified and tested on hardware.)
