Add web UI (#7151)

AI slop PR to add the initial skeleton of a Vortex web explorer.

* It creates a vite + TS + react + tailwind project, based on the styles
of vortex.dev
* A vortex-web-wasm crate for exposing a limited WASM API to Vortex.
* Drag-n-drop / browse for Vortex files, opens the file and displays row
count and dtype

TODO:
* Explore if this is the right way to setup previews. We need to
manually deploy since we must build the WASM asset.
