V45.23: fix Bug 4 (solo/mute khong tac dung o PIANO ROLL tab) - preview MIDI (keybed vkbNoteOn + hardware attachMidiHandler NOTE_ON bridge/SonicSF fallback) bo qua trang thai mute/solo cua MAIN/SECTION context: track muted hoac solo-out van phat am khi bam phim o PR tab. Them gate computeTrackAudibleGain vao 4 nhanh preview (bTracks, arSubs, armedTracks, vkb targets) - dung semantics nhu scheduleMidiNoteDispatch solo_guard (timeline da dung tu V45.21). vkbNoteOff/note-off bridge KHONG gate (phai kill note dang giu khi mute giua chuong). marker solo_guard block midi ch= p= cho dbg. v=202608311716
