Fixes #592

Overview

Implementation detail

The dialog is a vite internal web component that gets automatically triggered by its WebSocket connection.

In order to make this feature working I had to "hack" a little bit the current implementation

1. Since most of the compilation errors causes a failed SSR I created a fallback_html file that gets injected in .tuono/index.html that simply renders the project client side and open the connection to the vite server.
2. There is no a straighforward way to override the defaul vite error overlay. I followed the same implementation as astro (as suggested by one of the vite maintainers HMR overlay customization vitejs/vite#19552)

Implementation split

1. Build index.html from tuono CLI
2. Build error-overlay.ts component in the vite build
3. Add e2e test for the overlay (this caused issues, will do it in a separate PR)

Screenshot

For this iteration the overlay is just a clone of the vite one. In the future we might need to refactor the UI in order to make it more tuono style like. No changes to the current PR should be required

Overall this looks pretty good. I don't understand the removal of the class fields on the ts side. Would you be able to tell me more about that?
