feat(recording): rewrite device setup, fix video stop, update modeline icons

Video stop fix: kill wf-recorder (producer) first on Wayland so ffmpeg
gets clean EOF, then signal process group. Replaces sit-for with
poll-based wait-for-exit. Fixes zero-byte output files.

Device selection: rewrite quick setup to show all available mics with
PulseAudio descriptions, auto-detect default sink monitor for system
audio. Skip confirmation dialog, add Cancel option to mic list.

Modeline: replace red dot emoji with nerd font icons (mic/camcorder).
Rename quick-setup-for-calls to quick-setup, rebind C-; r s / C-; r S.

173 recording tests pass (was 165).
