* [PBE-1710] make example app Firebase friendly

* [PBE-1710] support reject.reason & show notification

* fix ios, improve setup

* support pronto-staging

* write openapi script + generate new API

* fixed accepting incoming call during another call (or outgoing call)

* Update packages/stream_video/lib/src/core/client_state.dart
