Kiali test in BB CI is inconsistent

Reference the "passed with warnings" runs on https://repo1.dso.mil/platform-one/big-bang/bigbang/-/jobs/7306903

On the upgrade job:

     CypressError: `cy.visit()` failed trying to load:
https://kiali.bigbang.dev/
The response we received from your web server was:
  > 503: Service Unavailable

• Suspect this may be the kiali pod/webservice taking some time to load after upgrading to the new version?

On the clean install:

     AssertionError: Timed out retrying: Expected to find element: `#Graph`, but never found it.

• Based on the job artifacts it appears that it times out and maybe need to add some more time in the cypress test to account for things at the BB level

AC:

• Cypress test / CI updated to be more resilient (better wait times, etc?)
