Add Bluetooth audio permission support for Android 12+ and VAPT security fixes

[sapta100ms]

Summary

• Add BLUETOOTH_CONNECT permission to Android manifest for Bluetooth audio device support on Android 12+
• Update native Android SDK to 2.9.83 which fixes audio device routing on the API 31+ path (adds AUTOMATIC
  to device list, simplifies audio manager selection)
• Request BLUETOOTH_CONNECT runtime permission in room kit's permission flow so Bluetooth headsets are
  discoverable during calls
• Revert minSdkVersion bump (29 → 24) in example app
• VAPT fixes: set exported=false on broadcast receivers, add root/jailbreak detection via safe_device

Context

On Android 12+, BLUETOOTH_CONNECT is required to enumerate connected Bluetooth audio devices. Without it,
the native SDK's audio manager couldn't detect Bluetooth headsets, causing them to be missing from
getAudioDevicesList(). The native SDK (2.9.83) also now always includes AUTOMATIC in the device list on the
API 31+ path, matching the Legacy path behavior.
