fix(ci): resolve CI build failures for audio dependencies

- Add libasound2-dev to Ubuntu CI workflows for ALSA support (cpal crate)
- Add opus to macOS CI for audiopus_sys build
- Remove unused imports in wraith-chat integration_tests.rs:
  - std::time::Duration
  - GroupInfo, GroupMember
  - VideoCallError, VideoCallInfo
  - CallInfo, VoiceCallError
- Fix unused variable warning (manager -> _manager)

These changes fix CI runs #308 and #309 which failed due to:
1. alsa-sys build failure on Linux (missing libasound2-dev)
2. audiopus_sys cmake failure on macOS (missing libopus)
3. Unused import/variable warnings treated as errors with -D warnings
