feat!: switch to tailwind 4 and shadcn-vue

- tailwind is eventually to replace bulma.
- basics are working
- reku-ui and shadcn for components library
- custom smile styles moved in src/css/smile.css
- shadcn components in src/uikit
- not backward compatible
- not complete (need to migrate existing components to tailwind and redesgn ui)
- experiment to see if can replace dashboard function
- iconify icons (huge selection) and unplugin to make it easy to use them
- not documented
