Next auth follow up tasks

[arkid15r]

Here is a list of changes we need to make in order to keep it in a good shape:

• update CI/CD workflows with valid env names (frontend auth related envs for staging/production)
• implement it in a way it'd work for contributors w/o GitHub application set up
• make the UserMenu look consistent w/ existing dropdown menu (Community)
• fix e2e tests and figure out whether it's possible to keep the turbo mode for tests
