fix: PIANO_ROLL activeTracks resolves main tracks, not section

Browse Source 
When PIANO_ROLL sub-tab is opened from SECTION-TAB,
activeTab switches to midi_xxx, so activeTracks fell
back to main project tracks. Section trackIds don't
exist in main tracks -> dropdown empty, ghost layers
empty, instrument data wrong.
Fix: check subTabs for PIANO_ROLL type, resolve parent
section tab from parent_tab_id, return its tracks.
