Refactor import statements for ResponseBase in API routers

- Updated import statements in the following files to import ResponseBase directly from models instead of models.response:
  - routers/api/v1/share/__init__.py
  - routers/api/v1/site/__init__.py
  - routers/api/v1/slave/__init__.py
  - routers/api/v1/tag/__init__.py
  - routers/api/v1/user/__init__.py
  - routers/api/v1/vas/__init__.py
  - routers/api/v1/webdav/__init__.py

Enhance user registration and related endpoints in user router

- Changed return type annotations from models.response.ResponseBase to models.ResponseBase in multiple functions.
- Updated return statements to reflect the new import structure.
- Improved documentation for clarity.

Add PhysicalFile model and storage service implementation

- Introduced PhysicalFile model to represent actual files on disk with reference counting logic.
- Created storage service module with local storage implementation, including file operations and error handling.
- Defined exceptions for storage operations to improve error handling.
- Implemented naming rule parser for generating file and directory names based on templates.

Update dependency management in uv.lock

- Added aiofiles version 25.1.0 to the project dependencies.
