Enable host OTA over BLE and harden ESP-NOW slave distribution.

Browse Source 
Allow the same staged firmware upload path on BLE as UART, fix distribute stack/event-group crashes, and recover sticky slave OTA sessions instead of failing with err=4.

Waits for **ready** after start (~30 s erase), sends 200-byte `OTA_PAYLOAD` frames, reads **block_ack** every 4 KiB, then `OTA_END`. The master then distributes to all available slaves (no extra host traffic); **success** is reported only when that finishes. Allow several minutes for large images. Reboot master and slaves to boot the new firmware.
