feat(audio): add the Audio source dropdown to the welcome screen

The opening screen only had Volume + Video speed — no way to pick the sound mode before launching. Add a welcome Audio dropdown (None/Soundtrack/Music) mirroring the panel; applyWelcomeToPanel carries the choice into the session on launch, None greys the welcome Volume, and ?audio= presets it on the welcome screen too. +4 e2e (welcome-audio.spec.ts).
