feat(api): add live status tracking for speakers and BGP sessions

- Introduced new schemas for `SpeakerLiveStatus`, `BgpSessionLive`, and `LiveSpeakerPoll` in OpenAPI documentation to support live status queries.
- Enhanced the `/v1/speakers` endpoint to include a `live` query parameter, allowing retrieval of real-time speaker and BGP status.
- Updated the HTTP API to collect and return live status data for speakers, improving monitoring capabilities.
- Modified frontend components to display live status information, enhancing user visibility into speaker health and BGP session states.
- Added a new endpoint `/v1/bird/status` for retrieving the local BIRD status, further enriching the network monitoring features.
