fix(openapi): avoid duplicated anyOf refs from shared app-level responses 

The OpenAPI generator performed only a shallow copy of
`additional_response`, causing nested objects (e.g., `content`)
to be shared across all routes during openapi generation. When 
`deep_dict_update()` merged schemas for each route, the 
shared `anyOf` array accumulated duplicate $ref entries. 
Switching to a deep copy ensures each route processes an
isolated response definition and prevents duplication.
