[FEATURE] Modernize tree rendering and implement RTL and dark mode

The SVG based renderer for the page, file and select trees has been
replaced by a HTML based one. It uses reactive rendering based on
lit's component model.

Using HTML and CSS rendering offers more flexibility than SVG,
so that RTL and dark mode support could now be implemented.
