Ensure /clear and panic triple-tap delete media files

Browse Source 
Fix: /clear command and panicClearAllData() now properly delete media files

1. /clear (triple-tap on chat):
   - Deletes outgoing media (voice notes, images, files)
   - Conservative: only our sent media, preserves received media
   - Runs in background to avoid UI freeze

2. panicClearAllData() (triple-tap on bitchat/ header):
   - Deletes ALL media files (incoming + outgoing)
   - Removes entire files directory and recreates structure
   - Ensures complete data wipe for emergency scenarios

Both operations run async on .utility queue to prevent blocking UI.
