fix(mobile): migrate expo-av to expo-video and expo-audio

expo-av has no SDK 56 compatible release, and its EXEventEmitter.h
interface was removed from expo-modules-core, so the iOS release
archive fails compiling Pods/EXAV. Move video playback to
expo-video's useVideoPlayer/VideoView, and audio playback and
recording to expo-audio's createAudioPlayer/AudioModule.AudioRecorder,
preserving existing controls, mute/loop/resize behavior, and the
recording audio session configuration.
