Fix e2e timeout: add 30s kill timer to Chrome, increase wait to 35min

Chrome headless can hang indefinitely if the page doesn't load.
Wrap all Chrome calls with `timeout 30` to kill after 30 seconds.
Increase the workflow wait loop from 25 to 35 min and job timeout
from 30 to 45 min, since OctoPrint can take 10+ min to start on
slower CI runners.
