fix(tests): add /users/me/regions/ mock to resolveOrgAndIssueId tests

The tests mocked globalThis.fetch for /organizations/ and /projects/
endpoints but not /users/me/regions/. When getUserRegions() got a 404
from the mock, ky threw an HTTPError which listOrganizations caught
and fell back to the non-region path. On certain CI runner images, this
error-fallback code path fails. Adding an explicit regions mock avoids
the error path entirely and makes the tests deterministic.
