Fix active source detection by including team names in lookup

- Update streams API to join with teams table and return StreamWithTeam data
- Modify stream lookup maps to generate proper stream group names with team prefixes
- Format: {team_name}_{stream_name}_stream to match obsClient.js logic
- Update type signatures throughout to support team_name and group_name fields
- Now properly matches text file contents with database streams for dropdown selection
