Portal target registration

Select Add Tgt(AP) to start AP mode and register a receiver MAC from a browser at 192.168.4.1.

Persistent settings

Critical parameters are saved via NVS so reboot does not reset field tuning.

Telemetry callback path

Optional receive callback allows reply packet parsing to confirm link quality and carry compact sensor feedback.
