fix: drag&drop many files, layout split, virtual scrolling, keyboard selection

- Use webUtils.getPathForFile (Electron 33+) for reliable file paths
- Use Set for O(1) dedup on large file drops
- Fix flex layout so Files panel stays visible with many queue items
- Fix virtual scrolling viewport height and range cache reset
- Add Ctrl+A (select all), Delete (remove selected) keyboard shortcuts
- Fix Shift+Click range selection to work with virtual scrolling
