Took hints from TTA and moved to ngx_env builder plus some tweaks to the angular.json file to make it more like TTA's
I've tested this locally on: localhost:3333 -> UI works localhost:3334 -> UI works localhost:3335 -> BE responds with a status indicating that it works
I've also done test deploys to dev and prod systems and it works there as well.
Just to be safe, start with make clean and all the make steps before running docker compose up to make sure all the dependencies are rebuilt for Angular.
