feat: Soundboard Plugin + Radio Globe Fixes

- Add Soundboard plugin (full Jukebox port): server + frontend + CSS
- Fix Radio Globe: swap geo coords (API returns [lng,lat] not [lat,lng])
- Fix Radio stations showing "Unbekannt": use item.page.title + fix channel ID regex
- Add DirectMessages + MessageContent intents for DM commands
- Register SoundboardTab in App.tsx with scoped theme/card-size CSS vars
