fix(05-jamtrack): pass jamServer to all loadJamTrack calls

Issue: jamServer was undefined in downloadJamTrack thunk
Root cause: One loadJamTrack call in handlePlay was missing jamServer parameter

Fix:
- Added jamServer to loadJamTrack call on line 194
- Added jamServer to dependency array on line 384
- Removed debug logging

All loadJamTrack calls now properly pass jamServer with subscribe/unsubscribe.
