CHW-4314 OrgSlugRequired

org-scoped URL required: /repository/@{org-slug}/{repo-name}/...; legacy URLs without the org slug are disabled on this instance

Default message: org-scoped URL required: /repository/@{org-slug}/{repo-name}/…; legacy URLs without the org slug are disabled on this instance
HTTP status: 400 (client)

Problem. CHAINSAW_REQUIRE_ORG_SLUG=true and the request used the legacy /repository/{repo}/... shape. Cause. The operator has disabled legacy URLs so every request must name the org explicitly. Fix. Switch the client to /repository/@{org-slug}/{repo}/.... HTTP 400.
