Host the `data-browser` assets / JS bundles

[joepio]

Currenlty, atomic-server depends on GitHub Pages for serving the front-end, because this line is present in the .html:

  <script src="https://joepio.github.io/atomic-data-browser/dist/index.js" type="module"></script>

The advantage of this is that I can update the version for all servers, and possibly fix things that are broken.

The downsides:

• Depends on me not breaking things (especially for older server versions!)
• Depends on Github not being down
• Depends on having a working internet connection (which Atomic-Server actually doesn't require - as long as all resources are already present in the store)

So I want to include these files, ideally in the single executable Rust binary.
But how? The source code is in another repository, and the build process is separate.

Ideas:

• Use rust-embed to include a directory https://crates.io/crates/rust-embed
• Host it using actix-files
• https://github.com/kilork/actix-web-static-files or https://lib.rs/crates/actix-plus-static-files

Fetch them as part of compilation, make a bunch of Actix endpoints

• Lots of seperate files, duplicate code

I could add a script that runs yarn build from atomic-data-browser and then copies all the files to the atomic-server/static/browser folder. This folder can then be hosted using actix-web-static-files.

I considered using rust-embed, but combining that with Actix would be quite verbose. I'd need to manually create routes for every single asset.

Second option: actix-web-static-files. Unfortunately, the docs indicate that this isn't even running on actix_web 3.0, let alone my 4.0 branch. Probably means diving into this crate, making it compatible with latest version.

Third option: bundle with Tauri. Would only work in desktop situations, and would not solve the problem for server version.

Tried actix-web-static-files. Indeed needs update. waits on stable v4 of actix-web. kilork/actix-web-static-files#47

Since I just rolled back actix to 3.x, I could retry this.
