Isolate the comments e2e pack in its own pond (#92)

The shared fixture pond accumulates grants from earlier packs in the
same CI job, so "fixture-editor is only a reader" did not hold there and
the policy test failed in CI while passing locally. A Site Admin now
lifts fixture-user's additional-pond quota for the run, the pack
provisions a fresh pond and page, and tears both down afterwards; the
policy PATCH is also asserted.
