chore: workaround for newer cypresses
chore: workaround for newer cypresses

unfortunately we're not very good in loading our resources. starting from 3.5.0
a bug in cypress was fixed to recognize this. now we never actually get a page
load, because of weird assets or the secrets-API not responding in our
system-tests(don't know why that is - but it seems to be a frequent issue).

we now give our system-tests 10 minutes to complete - each.
