chore: migrate to Vite and Bun to build the frontend

[Unix4ever]

Dropped some dependencies which no longer worked:

• monaco-editor-vue3 - replaced with a tiny wrapper.
• polyfill for streaming classes - replaced with vite plugin for polyfills.
• buffer - replaced base64 encoding with calls from the fetch.pb.ts.

Dropped the code that sets up monaco in main.ts in favor of Vite monaco plugin that does that for you.

Updated monaco-yaml as the old version didn't work with Vite.

Switched from Jest to bun:test.

Use TypeScript in the tailwind config, as it imports colors.ts now. Had to use TypeScript for colors as Vite can't import CommonJS modules.

Add eslint linter to the lint dependencies, enable a bit more linters and fix all detected errors.

Fixes: https://github.com/siderolabs/omni/issues/294

I personally love the -34k lines

Do we need to have a matching kres update?

yep, will create the PR for it now

I'll cut 0.38.0-alpha.0 with this change and roll it out to sandbox. We need to properly test that no UI features were broken after this change, as I've basically recreated vue project from scratch.
