Speaker worked but the earpiece was silent, and call audio flickered on speaker
then dropped. Causes: (1) the category set .defaultToSpeaker, so overrideOutputAudioPort(.none)
fell back to the loudspeaker instead of the receiver; (2) setSpeaker re-ran
setCategory+setActive on every toggle mid-call, tearing down the audio unit WebKit's
WebRTC engine was using and silencing the earpiece route.
Fix: drop .defaultToSpeaker (drive the port explicitly), make setSpeaker flip ONLY
overrideOutputAudioPort, and observe routeChangeNotification to re-assert the chosen
route when WebKit reconfigures the session at call start / device change.

Capacitor derives the pod name from the npm package name (audio-route -> AudioRoute)
and writes 'pod AudioRoute, :path => ../../plugins/audio-route' into the generated
Podfile. CocoaPods then requires a file literally named AudioRoute.podspec whose
s.name is 'AudioRoute'. The old AudioRoutePlugin.podspec (s.name AudioRoutePlugin)
caused the Codemagic build to fail with 'No podspec found for AudioRoute'.

Device telemetry proved the app-embedded AudioRoute class never registered (not in
Capacitor.Plugins) — appending a CAPBridgedPlugin to AppDelegate.swift gets stripped/undiscovered
in release builds. The plugins that DO register (Share, Camera, Filesystem) are all npm packages
wired by cap sync. So AudioRoute is now a local plugin package (mobile/plugins/audio-route,
file: dep in mobile/package.json) with a podspec + CAPBridgedPlugin Swift — cap sync adds its pod
and Capacitor registers it like the others. load() sets the launch speaker default; setSpeaker({on})
overrides the output port. inject-audio.js no longer injects the plugin class (would duplicate);
it keeps only the AppDelegate launch default as a fallback.
