Disable server-side rendering in UI development mode

[lemmih]

Summary

Right now, we rebuild both the front end and back end for every change, adding latency to the dev loop. Disabling server-side rendering and only building the front end when doing UI work may be beneficial. This only works when not adding or changing the server-side functions.

Alternatively, we could build the front end and back end in parallel. Right now, they're built sequentially.

Completion Criteria

• Benchmark compiling the frontend and backend in parallel.
• Add an environment in wrangler.toml to compile only the front end. This requires disabling server-side rendering.

For context, here's some timing data on my local machine:

CSS gen: 1.3s
Backend: 5.5s
Frontend: 3.8s

These steps are independent of each other and could be done in parallel. Reloading in 5s rather than 10s would be nice.

We can also skip the custom CSS file when developing. We can reference the non-minified Tailwind CSS file. However, this file is quite large and shouldn't be used in production.
