Resolves issue 1941, Corrects legacy organization response schemas

[Ewgna]

Closes Issue 1941

Summary

Updates the OpenAPI contract for legacy organization endpoints so it matches actual behavior; GET /api/org and POST /api/org return only legacy-formatted organization responses, registry-formatted responses no longer listed as an alternative

Important Changes

src/controller/org.controller/index.js

• Replaced the oneOf response schemas for GET /org and POST /org with legacy version

api-docs/openapi.json

• Regenerated the OpenAPI with legacy-only responses

test/unit-tests/org/openapiOrgResponseTest.js

• • Likely unneeded, short test to confirm both document the correct legacy response

Testing

• Ran the OpenAPI response unit test.
• Ran ESLint for the updated controller and test files.
• Verified the generated OpenAPI JSON is valid and contains the expected response schemas.

Notes

• No runtime behavior is changed
