feat(api): enhance peer session tracking and error handling

- Added `PollError` field to `peerSessionOnSpeaker` and `liveSpeakerPoll` types to capture polling errors for speakers.
- Updated `matchPeerOnSpeakers` function to handle polling errors and adjust session state reporting.
- Modified frontend components to display polling error messages alongside session states, improving user visibility into peer connection statuses.
- Enhanced API response structure to include live speaker polling information, facilitating better monitoring of speaker health.
