[nick-skriabin]

Introducing new Homepage and integration of Tailwind and shadcn.

Documentation for the new UI component and usage of Tailwind is coming separately. Will cover the usage of the components, how to add new ones, how to properly use Tailwind in the context of Label Studio.

There will also be some follow up refactoring to cleanup transition period inconsistencies.

One line description for 100+ files with lot of new components, new approaches, changes without explanations, etc?
Please let's be diligent and respect the quality of our codebase. I already see a bunch of issues and asking for another round of reviews.

[hlomzik]

Unfortunately there are still things to fix. Plus we have to run all tests again
