Fix Automated Blackbox Testing github actions

Fir our svelte CMS project code at https://github.com/SveltyCMS/SveltyCMS/tree/next and we need a fully suite of automated Blackbox tests integrated directly into the GitHub workflow. Currently test don't pass.

The goal is to cover every major module—user authentication, content management, and the public API endpoints—so that each new pull request is automatically validated before merge.

Local testing should never work with live data (config/private.ts)

Whitebox is only unit tests to test code and already passing

Blackbox testing for integration and e2e (playwright) are failing

Playwrite tests can be rewritten if faster

Testing should be done on your git branch 1st.

When all is GOOD & Passing, you create a new pull request to next branch
