chore: remove unused dump_openai_response and dead test helpers

- Delete client.dump_openai_response (and its import json): never called
  from any production path (connect_node, text_gen_node, image_to_text_node,
  routes, __init__); existed only as a debugging aid.
- Delete its test (test_dump_openai_response_branches in test_client_full.py)
  and the now-orphaned `import json` in that file.
- Delete make_response_with_output_text / make_response_with_output_items
  from tests/helpers/fakes.py: defined in the initial test scaffolding
  commit but never imported or referenced by any test module.

All 68 tests pass; branch coverage holds at 96.93 % (> 90 % required).
