feat: parent notes (file bookmarks with children) + no default icon

- File bookmarks can now have children, rendered with a chevron
- Group bookmarks can have an associated filePath; clicking opens the file,
  clicking chevron toggles collapse
- 'Add as parent note' option in header context menu creates a group
  with the current file linked
- 'Add child note' option in group context menu creates a sub-group
  with the current file linked (parent note pattern)
- Default icon changed from 'file'/'folder' to '' (no icon)
- Chevron click always toggles collapse regardless of type
