feat(engine): fix SF2 path resolution, add synth_engine struct and fallback chain

Browse Source 
- Fix SF2 path: search upload dir, system dir, static dir (backward compat)
- Add synth_engine struct parsing with flat field fallback
- Add 3-level fallback: selected SF -> default SF -> oscillator synth
- Write synth_engine in setTrackInstrument UI setters
- Pass synth_engine context to client SoundFontPlayer and AI gateway
