revert: section tracks inherit parent instrument, auto-loads SF prog0

Browse Source 
Previous fix f2ac70e inherited instrumentId/program/name
from parent MAIN track. This causes SECTION-TAB to auto-load
program 0 of whatever SoundFont is loaded on MAIN, even
though user didn't select any instrument for the section.
Section tracks now keep null instrument + synth_engine
undefined. User can still load instrument manually via
Synth button (routed by updateActiveTracks fix).

### [2026-07-28 08:17] Task: Kế thừa instrument từ MAIN track vào section sub-tracks
- **Tóm tắt thay đổi:** Fix fallback branch `handleEditSectionInTab` — khi section chưa có tracks riêng, clone tracks kế thừa `instrumentId`, `instrumentProgram`, `instrumentName` từ parent MAIN track thay vì null/undefined. Trước đây instrument bị xoá (null/undefined) → section không có instrument nào.
### [2026-07-28 08:27] Task: KHÔNG auto-load instrument MAIN vào SECTION-TAB track
- **Tóm tắt thay đổi:** Revert kế thừa instrument từ parent MAIN track. Section tracks giữ `instrumentId: null, instrumentProgram: undefined, instrumentName: null, synth_engine: undefined`. Trước đây kế thừa instrument (f2ac70e) → SECTION-TAB auto-load program 0 của SoundFont từ MAIN. User tự chọn instrument trong SECTION-TAB qua Synth button (đã hỗ trợ qua `updateActiveTracks` routing).
- **Các file ảnh hưởng:** `app/static/js/app.jsx`, `app/static/js/app.precompiled.js`
- **Ghi chú/Test (nếu có):** `npm run build` pass. Load instrument trên MAIN track → mở section tab → MIDI items kế thừa instrument từ parent track.
- **Ghi chú/Test (nếu có):** `npm run build` pass. Load instrument MAIN → mở section tab → section tracks KHÔNG có instrument.
