Nemanja Nedeljkovic 6507b8f36b feat(pm5): hf tune --rgb / lf tune --rgb - antenna RGB as a tuning meter 
Adds an opt-in `--rgb` flag to the continuous `hf tune` / `lf tune` commands that
mirrors the antenna tuning level on the PM5 antenna RGB LED: blue = low, green =
mid, red = high, tracking the on-screen bar so you can find coupling (e.g. an
implant) by feel without watching the screen.

The colour is computed client-side from the same per-iteration voltage / running
peak the bar uses (so it matches the bar and auto-scales), and pushed to the
device via a new dumb CMD_PM5_RGB_SET {r,g,b}. That command is handled (#ifdef
PM5) by a dedicated AT32 RGB HAL module, common_arm/rgb/{rgb_apis.h,
rgb_hw_at32.c} (RgbLedSet(), I2C controller @ 0x48), wired into the armsrc
Makefile/CMake as SRC_RGB for PM5 only - so no other platform is affected and no
hardware code lands in shared files.
