feat: local call recording (your mic + incoming mix) to WAV

Public Access

Opt-in recording of the full call as you experienced it. New dep-free
src/audio/recorder.rs: a canonical mono S16LE WavWriter (header patched on
finalize) plus a Recorder that buffers your transmitted mic in a bounded FIFO
and sums it, sample-aligned, with each incoming-mix frame the playout mixer
produces. The two independently-clocked streams stay aligned via the FIFO
(capped at ~200ms so drift lag can't grow without bound); silent stretches
record the incoming mix alone. Dep-free UTC timestamp -> sortable filename.

Wiring: CoreCommand::SetRecording toggles an Arc<Mutex<Option<Recorder>>> gated
by an is_recording flag (so the capture/mixer hot paths only lock while actually
recording); capture pushes post-gate mic, the mixer writes the pre-deafen mix.
Recording finalizes on stop, room leave, and room switch. UI: a Record/Stop
button in the controls and a red "● REC m:ss" pill in the room header;
core-confirmed Recording{Started,Stopped} events drive the UI flag so a failed
start can't lie. Files land in ~/peerspeak-recordings/.
