fix(oauth): address Greptile P2 findings on #25923

- Drop the redundant decorator-level ``dependencies=[Depends(user_api_key_auth)]``
  on all 8 OAuth endpoints (4 each in chatgpt/copilot). The same dependency
  is already injected as a parameter, which runs it and binds the result —
  FastAPI's dependency cache makes the decorator-level duplicate a no-op at
  runtime, just visual noise.
- Finish the @tremor/react → antd migration in ``credentials.tsx``: rename
  the ``AntdButton`` alias to ``Button`` and remove the ``Button`` entry
  from the @tremor/react import, so the top-level "Add Credential" button
  also goes through antd. No rendered changes (antd Button's children +
  onClick API matches what that call site already used).
