Add studio mode status display and preview/program indicators

- Enhanced obsStatus API to include studio mode and preview scene information
- Updated Footer component to show studio mode status (STUDIO/DIRECT)
- Added preview scene display in footer when studio mode is enabled
- Implemented dynamic scene button states showing Program/Preview/Both status
- Scene buttons now clearly indicate preview vs program with distinct colors
- Added proper state management for studio mode and preview scenes
