Consolidate soundboard categories and improve layout

- Merge all people categories (JOSH, LANX, MUTT, etc.) into NERDS section
- Consolidate TV & movie categories into single TV & MOVIES section
- Maintain alphabetical order within all sections
- Update soundboard to show 4 categories per row for cleaner layout
- Remove verbose category list from soundboard interface
- Add emojis to category headers for better visual appeal

Soundboard now shows:
- 🔉 GENERAL - Common/utility sounds
- 🤓 NERDS - Gaming, streaming, and personality sounds
- 🎥 TV & MOVIES - All show/movie clips combined
- Clean 4-button layout per row
