test(webapp): make the browser session-stream leg CI-robust

ericallam · ericallam · commit f2805d02ab7f · 2026-07-24T11:51:54.000+01:00
Download Chromium without `--with-deps` (the apt step exited 100 on the CI
runner and aborted the whole e2e job before any test ran) and skip the leg
if the browser still can't launch, so a browser hiccup can never take down
the wire-protocol suite.
