feat(ios calls): drop unreachable earpiece from route toggle; Speaker <-> BT/headset

Browse Source 
Proven via device telemetry: inside a WKWebView, WebKit owns the WebRTC audio unit and
forces the loudspeaker; overrideOutputAudioPort(.none) is a no-op (route settles on
Speaker 1.2s later), so the built-in earpiece cannot be selected. Present only what
actually works on iOS: Speaker, and Bluetooth/wired headset when connected. bzApplyRoute
now maps only 'speaker' to the loudspeaker override; bt/headset use the default port.
Coerce any stale 'earpiece' pref to speaker on iOS. Also strips the route debug telemetry.
Other platforms keep the earpiece option. build batch147.
