The suites connected to localhost:<published port>, which works for a developer
but not on a containerised runner: published ports live in the host's network
namespace, so the runner container gets connection refused.
Run them from inside the stack instead, against the gateway by service name.
SITE_BASE_URL and SITE_HOST_HEADER make that possible without weakening what is
under test: the Host stays "localhost", so the gateway's host check and
TrustedHostMiddleware see exactly what a localhost run produces, and the tests
that deliberately send their own Host still override it.
S3_PUBLIC_ENDPOINT has to agree, because presigned URLs are signed against it
and the signature covers the host, so it cannot be rewritten afterwards. CI
points the whole stack at http://storage:9000 so the URLs it hands out are
reachable by whoever follows them.
The browser suites still need Chrome to reach the stack from the runner, which
the same namespace split prevents. They now check reachability and skip with a
warning instead of failing with a bare connection error; recorded as ROADMAP
5.10, since they are the only coverage for the artwork editor.
Verified both ways: the six suites pass inside the network, and an unchanged
developer localhost run still passes, as do both browser suites locally.
