Calls were routing to the quiet earpiece. ios-patch.sh now runs a Node helper (Node 20 is
already in the build env) that injects an AVAudioSession .playAndRecord/.voiceChat category with
.defaultToSpeaker + Bluetooth into the generated AppDelegate. Tolerant: exits 0 and no-ops if the
template differs, so it can never fail the Codemagic build. Verified locally against the Cap 7
AppDelegate template — injects correctly and is idempotent. First pass; if WebRTC re-grabs the
session mid-call on device, a follow-up plugin will re-assert .overrideOutputAudioPort(.speaker).
