fix: group drag cross-track uses live prev state for index mapping

+### [2026-07-29 10:58] Task: Fix group drag cross-track stale track index bug
+- **Tóm tắt thay đổi:** Sửa `trkIds` dùng `prev.map(tr => tr.id)` (từ live state trong callback) thay vì `activeTracksRef.current`. Sửa insert section dùng `for` loop tìm srcItem đúng thay vì `flatMap` sai.
