Isolate the remote registry in tests

Endpoint resolution consults remembered remotes, so tests that assert the
bare-domain :443 default failed on any machine with an explicit-port remote
remembered for the same host, while passing in CI. That made a real behavior
difference look like a local-only flake.

Isolate the registry for the whole suite instead of patching the two affected
tests, since any test touching endpoint resolution has the same hidden
dependency. Tests that need remembered entries still override the path.

Also replace the hardcoded personal remote host with a documentation domain.
