ci: Make end-to-end testing independent of development environments (no-changelog) (#4709)

* use user-folder override consistently everywhere, including for the `.cache` folder

* use consistent config for e2e tesing, skipping config loading from env and config files

* simplify all the cypress commands, and run all e2e tests on master
