Добавлен кастомный WebRTC AAR для CI + фиксы звонков

- libwebrtc-custom.aar закоммичен (был в .gitignore, CI использовал Maven без relative vtables → SIGSEGV)
- Фикс ForegroundServiceDidNotStartInTimeException (safeStopForeground)
- Фикс бесконечного "Exchanging keys" (ретрай KEY_EXCHANGE, auto-bind account)
- Фикс "Unknown" при сбросе звонка (stop ForegroundService до сброса state)
- Decline работает во всех фазах звонка
