Title: Fix Bugs, Enhance Compatibility, and Improve Defaults in Pull Request

[jayxuz]

This pull request addresses the following changes:

• Fixed a bug where the interface would throw an error when the input request parameter was in the format of List.
• Changed the default HOST from localhost to 0.0.0.0 to allow external access.
• Modified the default value of NORMALIZE_EMBEDDINGS to True.
• Fixed an issue where the HuggingFaceBgeEmbeddings couldn't be called when loading a local model.
• When no model name is provided, it now defaults to the model defined in DEFAULT_MODEL_NAME.
• Added attributes to the returned class to maintain consistency with the OpenAI format.
• Added the dependency "uvicorn" for service startup.
• Improved Python version compatibility (tested with Python 3.8 to Python 3.10) by switching methods between **request.model_dump and **request.dict based on the differences in pydantic versions.

Please review and merge this pull request at your earliest convenience. Thank you!
