Move frontend build to a separate build stage

[alastair]

Allows us to build in parallel, speeding up build process Removes node from our main runtime image

Thanks for that @alastair! I think it might be great to do something like that, but we should provide an alternative to docker compose run --rm web npm run build as this will not work. This is used in local development when making changes to static src files. I guess we add a new service to the docker compose config which refers to frontend_build docker image stage? (and update the "static build" tasks in vscode workspace file)

@ffont this is resolved - build steps are correct if you want to run manually, and there's a profile to automatically build (taking advantage of the parcel cache) whenever you make a change to a file

That looks really nice @alastair ! Although the build is failing with something uv related?

[alastair]

yeah, this is a common build issue with pysndfile, I keep running into it. let's see if we can fix it once and for all

[alastair]

this is building now, I upgraded to the latest pysndfile.
There's a bug in their build script, but I submitted a patch, hopefully we won't need our workaround in the future. We can wait until next week to release this, in case some unexpected issue comes up with processing due to the upgrade.

Now it builds in less than 2 seconds, amazing!

Oups,
I merged without actually testing it, and now I see that the JS has errors :S
