Persist accelerometer deadzone in NVS across reboots.

Browse Source 
Each node saves its local deadzone on UART or ESP-NOW set; pod_settings loads and applies it after BMA456 init.

**Accel logging:** Samples are printed only when any axis changes by more than the **deadzone** (raw LSB) since the last logged sample (default **100**). This is a **software** filter on top of the sensor; it does not change BMA456 hardware thresholds.
**Persistence:** The local deadzone is stored in the **`nvs`** partition (namespace `powerpod`, key `accel_dz`) via `pod_settings.c`. Each node (master or slave) keeps its own value across reboot. Loaded at boot after `init_bma456()`; saved when set locally (UART `client_id = 0`, `all_clients` on master, or ESP-NOW deadzone on a slave).
**Configuration paths:**
| Path | Effect |
|------|--------|
| UART `ACCEL_DEADZONE` with `client_id = 0` | `bma456_set_accel_deadzone()` on the local node |
| ESP-NOW `SET_ACCEL_DEADZONE` | Same on a slave (no-op log path if sensor not installed) |
| UART `ACCEL_DEADZONE` with `client_id = 0` | Set + save local deadzone |
| ESP-NOW `SET_ACCEL_DEADZONE` | Set + save on the receiving slave |
| `make gotool-deadzone-set DEADZONE=… CLIENT=0` | Host shortcut for local deadzone |
**Logs:** `[BMA456] ACC X=… Y=… Z=…` when deadzone exceeded; `[BMA456] tap: single|double|triple` on interrupt.
