Add or Migrate to FrankenUI

[shroominic]

Franken UI is an HTML-first, open-source library of UI components based on the very popular shadcn-ui.

I think this could easily replace the default bootstrap ui or work as additional template.
Building on top of that would probaply increase the popularity of FastUI by alot because (almost) everyone loves how shadcn looks and sadly most people judge a book by its cover.
