Update project configuration and code structure

- Added '*.o' to .gitignore to exclude object files from version control.
- Modified Dockerfile to specify the application directory for Uvicorn.
- Updated setup.py to reflect the new source directory structure for Cython extensions.
- Adjusted E2E Docker Compose command to include the application directory.
- Refined type hints in ApiClient and Security classes for better clarity and consistency.

These changes enhance the project's organization and improve the build process.
