refactor: remove auth inherit and token handling from login request

- Remove 'auth: inherit' from POST request configuration
- Remove post-response script that set token environment variable
- Clean up documentation formatting

This simplifies the login request configuration as authentication
will now be handled via HTTP-only cookies instead of bearer tokens.
