feat: add Qwen Qwen-3 provider and update audio/media handling

- Introduce `Qwen_Qwen_3` provider in `g4f/Provider/hf_space/Qwen_Qwen_3.py`
- Register Qwen_Qwen_3 in `g4f/Provider/hf_space/__init__.py` and add it to `HuggingSpace`
- Update `MarkItDown` in `g4f/Provider/audio/MarkItDown.py` to accept and forward `llm_client` and `llm_model` kwargs; add async handling for `text_content`
- Modify audio route in `g4f/api/__init__.py` to pass `llm_client` for MarkItDown and set `modalities` only for other providers
- Adjust `OpenaiChat` (needs_auth) to merge media for upload and check for media presence before requesting images
- Change `get_tempfile` in `g4f/tools/files.py` to determine suffix from file extension using `os.path.splitext`
- Refactor provider listing and model mapping in `AnyProvider.get_models()` (g4f/providers/any_provider.py) to update provider order, support new `HarProvider`, initialize attributes, and guard against model_aliases being None
- Ensure `AnyProvider.create_async_generator` calls `get_models` before working with providers
