refactor: webapp ci

[GabenGar]

• added .dockerignore to webapp so it wouldn't dump the local build artifacts and node_modules folder into the image
• changed dockerfile so it would actually install with yarn and the package cache wouldn't bust on every source code change

@horahoradev
For some reason yarn couldn't fetch the packages when ran from the docker stack. Installs fine from the local setup though.
Does horahora use some kind of proxy and can you check if the webapp image builds for you?

[horahoradev]

There wouldn't be any proxy for yarn, no. It does build fine on the CI tests.

I don't see any issues with this... but I'll merge it tomorrow morning; apologies for the delay. Thank you for your contribution!

[horahoradev]

WOW!

[horahoradev]

so this way we won't have to reinstall deps when we change the src (lol). much better

[horahoradev]

oh, interesting, I hadn't heard of a dockerignore file

[horahoradev]

merged, thank you!
