Fix mock handlers to match gateway routing behavior

- OpenAI client → Claude model: gateway routes to /v1/chat/completions
  (not /v1/messages), so use setup_openai_chat_mock
- Responses API: gateway translates all requests to /v1/chat/completions
  on upstream with base_url providers, so use setup_openai_chat_mock
- Remove unused imports (json, pytest, setup_responses_api_mock)

"""Mock-based tests for the OpenAI Responses API (/v1/responses).
Tests passthrough to OpenAI, translation to chat completions for non-OpenAI
providers, tool calling, streaming, and multi-turn state management.
Tests translation to chat completions via the gateway, tool calling,
streaming, mixed content types, and multi-turn state management.
Note: The gateway translates all Responses API requests to /v1/chat/completions
on the upstream when using base_url-configured providers. Direct /v1/responses
passthrough is tested by the live e2e tests on main/nightly.
These tests require the gateway to be running with config_mock_llm.yaml
(started via docker-compose.mock.yaml).
