The common attenuation made playback too quiet. Inputs are now summed
without attenuation; docs note that loud simultaneous inputs can clip.

install.sh now sets the hostname (default radxa-mixer, --hostname or
--keep-hostname to override) after a successful install so Avahi
advertises NAME.local, and the web mixer listens on port 80. The web
server's host check already accepts HOSTNAME.local.

SBC medium, not the larger buffer, removed the headphone relay dropouts,
so cut dmix, bluealsa-aplay and alsaloop buffers to 200 ms and the
Shairport backend buffer to 0.15 s. Verified by listening (iPhone ->
headphones, with AirPlay mixed in) with no RTP loss or underruns.

One-shot bluetoothctl pairing exited before SSP finished, leaving the
headphone paired but not bonded, so it was lost on reboot. Pair inside a
single bluetoothctl session with a persistent agent, and clear temporary
pairings first. Document that SBC medium + 500 ms buffer removed the
iPhone -> Radxa -> headphone dropouts, verified by listening and logs.
