Multi-select, context menu, section strikethrough, rename/duplicate presets

- Multi-select strips with click, Ctrl+click (toggle), Shift+click (range, same zone)
- Right-click selected strip: context menu with Cascade CC, Assign Channel, Deselect All
- Right-click unselected strip: clears all selections
- Selection status label shows count and type (faders/toggles/transport toggles)
- Rename preset button added to preset row
- Duplicate preset button auto-generates new UUID
- Layout panel section buttons show strikethrough when hidden, normal when visible
- Renamed Preset Browser to Instrument Browser in UI
- Transport strips wired for multi-select and context menu
