Begin replatform of UI to React

[desertaxle]

This PR introduces the foundation for the replatformed Prefect UI. There's a lot here, but these are highlights:

• New UI bootstrapped with Vite and React
• New Typescript client generated from Prefect OpenAPI schema and integrates the generated client with @tanstack/react-query
• Adds several base components using shadcn/ui
• Adds a couple of example routes using @tanstack/router with query param validation using zod
• Adds a workflow to verify linting and formatting of the v2 UI

This PR also adds @aaazzam as a codeowner of the ui-v2 directory for reviews.

lgtm, though I'd like to not carry forward the state iconography. My preference is to roll as many lucide icons as we can stomache.

Cool, I can take those out.
