fix: main playback default program 0 loads MAIN SoundFont

Line 10283 same issue as 10393: when instrumentProgram is undefined (section cloned tracks), program defaults to 0. _playNoteFluid calls program_change(ch,0) on FluidSynth, which loads program 0 from whatever SoundFont is loaded (MAIN session's SF). Fix: pass undefined -> oscillator fallback for all tracks without assigned instrument.
