Fix ESP-NOW unicast by using sender MAC in client registry.

Browse Source 
Register slaves from recv src_addr instead of protobuf mac bytes, add
ESPNOW_UNICAST_TEST for path verification, restore unicast deadzone, and
expose unicast-test in goTool.

Slaves register when the master receives `SLAVE_INFO` on the matching network; `HEARTBEAT` keeps them marked available.
Slaves register when the master receives `SLAVE_INFO` on the matching network; `HEARTBEAT` keeps them marked available. The registry **MAC is always the ESP-NOW source address** (`recv_info.src_addr`), not the optional `mac` bytes in the protobuf (used only on the wire for debugging).
`slave_id` is the sender’s WiFi STA address last octet (`mac[5]`); it can collide across devices — use `gotool clients` and match the full MAC.
