CRASH: iOS terminates an app that receives a VoIP push without calling
reportNewIncomingCall. My re-ring 'fix' made the cancel path call completion() without
reporting -> crash. Always report then immediately end on cancel (a tiny ring blip is
unavoidable; a crash is worse).
MIC + earpiece: an ACTIVE CallKit call reserves the mic (WebView WebRTC gets a dead mic
+ earpiece routing). So on answer keep CallKit active only long enough to foreground the
app, then end it and fire 'callHandoff'; the WebView forces the loudspeaker and
re-acquires the mic (sfuSetMic off/on, retried while it finishes joining).
MISSED CALL: endDmCallByRoom now sends a plain missed-call banner to the callee when the
call ends unanswered (timeout / caller hung up before pickup); skipped on decline.
Server (missed banner) deploys now; plugin + web handoff need a Codemagic build.
