feat: pair controllers and show them in the app

Port the MT76 client functions (send_wlan, associate_client,
pair_client, set_client_key, remove_client) and wire the RX dispatch
into the session: EP IN frames are parsed, ASSOC_REQ associates a
controller (WCID plus chip programming), PAIR_REQ replies with
PAIR_RESP, and DISASSOC or client-lost removes it. The C API exposes
connected controllers and the app lists them by MAC. Bumps
xone_cli/xone_app to C++23: they were falling back to the default
standard once mt76.hpp started using std::span. Adds a unit test pinning
the WCID regions, the 32-byte rxwi, and the new frame control values.
