Closes #1295

[Copilot]

Pull Request Overview

This PR removes unnecessary information from the PATCH /responses/{responseID} request body by introducing a new EditResponse model and updating related request types and schema references.

• Introduced an EditResponse struct in openapi/types.go with Body, IsDraft, and ResponseId fields.
• Updated the JSON request body alias and swagger schema references to use EditResponse instead of Response.
• Adjusted tests and controller logic to consume the new EditResponse structure and remove duplicate data retrieval.

openapi/types.go:171

• [nitpick] Consider renaming the field 'ResponseId' to 'ResponseID' for consistency with Go naming conventions regarding acronyms.

ResponseId *int           `json:"response_id,omitempty"`

controller/response_test.go:975

• [nitpick] Ensure that the test validates the new ResponseId field; add assertions to check that ResponseId is correctly set in the response.
