chore: Dashboard cypress refactor

[adam-stasiak]

SUMMARY

I closed old PR (I thought I can reopen when ready but I forced push changes with data-test attributes from #11254 -then it was blocked by github) and resolved review suggestions from #11049.
I moved dashboard tests to use data-test attributes.

Couple of questions on the thread, but this is looking great thus far! Obviously there are some CI issues that will need to be investigated as well, so I'll keep an eye on any relevant changes.
