- Enhanced stream deletion with comprehensive OBS cleanup:
  - Removes stream's nested scene
  - Deletes browser source
  - Clears text files referencing the stream
  - Removes stream from all source switchers
- Enhanced team deletion to clean up all OBS components:
  - Deletes team scene/group
  - Removes team text source
  - Deletes all associated stream scenes and sources
  - Clears all related text files
- Fixed stream selection to use proper team-prefixed names in text files
- Added StreamWithTeam type for proper team data handling
- Improved browser source creation with audio controls:
  - Enabled "Control Audio via OBS" setting
  - Auto-mutes audio on creation
- Attempted multiple approaches to fix text centering (still unresolved)

Known issue: Text centering still positions left edge at center despite multiple attempts
