Implement Windows-style inline file/folder renaming and creation

- Remove popup dialogs for rename and new file/folder operations
- Add inline editing mode with input field replacing file name display
- Support both grid and list view modes for inline editing
- Key features:
  - Click file name to start editing
  - Enter to confirm, Escape to cancel
  - Auto-focus and select text when editing starts
  - Visual feedback with blue border on edit input
  - Cancel new items removes them from filesystem
- New file/folder workflow:
  - Creates with default name immediately
  - Starts inline editing automatically
  - User can rename or cancel (which deletes the item)
- Maintain full keyboard navigation and accessibility
- Preserve all existing selection and context menu functionality
