Send the comma's Bluetooth address in the head unit pairing request

LeaseAwarePhone (used for every wireless session) had no adapter() method,
so Supervisor._adapter_address() hit AttributeError, swallowed it, and
returned "". The Bluetooth-service pairing request was therefore never sent
(bluetooth_opened always logged phone_address: "").

A 2020 myChevrolet (head unit 2.46.1.6) through an AAWireless Two+ then
accepted and acknowledged video but never showed it. A real phone sends the
pairing request about 1 s into the session; the car shows Android Auto once
its hands-free link to that address is up.

Pass adapter() through to the wrapped BluezPhone. It is a read-only property
lookup, so it needs no phone-role lease, like devices() and device().
_adapter_address() now logs adapter_address_unavailable instead of failing
silently.

Tested on the car (session-000052): phone_address sent, pairing response
received, picture displayed, touch input worked, 20-29 fps fully acked.
