fix(frontend): resolve TypeScript type errors in repository pages

- commits.tsx: fix Unix timestamp (time_secs) not multiplied by 1000
- RoomMessageSearch.tsx: add explicit generic type for resp.data
- RoomPinPanel.tsx: make sender_id optional (string | null)
- message-list.tsx: remove unused index variable in map
- repository-context.tsx: use correct RepoInfo field names
- use-audio-recording.ts: use audioStream state instead of undefined var
- universal-ws.ts: rename unused id to _id
