fix: build node_modules into separate docker layer

[leon]

To optimize the docker build we want to build as little as possible. by first installing node_modules and then copying the app and starting it. We can cache a lot.

the first build took 68s and then since it can cache it only takes 25s. If we where to enable the nx cloud build, it would drop to < 10s.

I also added some convenience scripts and changes the html port to 80 so you can have the main app run on http://localhost
