Quiet pods no longer spam 100 Hz samples; mute wifi logs and throttle BLE
notifies during slave distribution so the wifi task stack does not panic.

* Polls accelerometer at 10 Hz; tap events arrive on BMA456_INT_GPIO.
* Accel logging is filtered in software (deadzone); slaves stream samples via ESP-NOW.
* Accel log + ESP-NOW stream share a software deadzone filter (emit on change).
