fix(audio): sync capability input selection when the user applies a device

Browse Source 
A stale feedBack.audioInput.selectedLogicalSourceKey (persisted by the
audio-session capability) survived device changes made in the audio
settings screen. The next plugin to open the 'selected input' (tuner /
note_detect on song start) re-applied the stale device via
audioInputOpenHandler, clobbering the engine's input mid-session —
seen in the field as guitar input going dead when starting a song
(vorrin logs: ASIO M-Audio input replaced by 'Microphone (WO Mic
Device)' ~0.5s after playSong, input level 0.0005).

Fix: after a successful device apply (Apply button and init auto-
apply), select the matching source in the audio-session capability so
its in-memory selection and persisted key follow the user's choice;
fall back to rewriting/removing the localStorage key directly when the
capability or source isn't available yet.
