Localized bar strings, signal-gated listening, warm microphone, animation styles

- The bar speaks the language being dictated ("Ouvindo…", "Escuchando…", …).
- Green now means real audio is arriving, not just that pw-record connected:
  a Bluetooth microphone sends silence while it switches profile, which is
  where the first words were being lost.
- Advanced → "Keep the microphone open": the stream is parked between
  recordings and a recording starts instantly with ~0.6 s of pre-roll.
- Settings → "Bar animation": bars, wave, pulse or dots.
- pw-record is shut down off the event loop so a cancel can never stall.
