This commit replaces hardcoded sensitive information, such as database passwords and secret keys, in the README and deployment documentation with placeholders and instructions to use environment variables. This change enhances security by preventing exposure of sensitive data in the codebase. Additionally, it updates the database session management to raise an error if the DATABASE_URL environment variable is not set, ensuring proper configuration for development environments.
This commit updates the `ARCHITECTURE.md` file to reflect the transition to a web-based application, including new features and system overview. Additionally, it introduces `AUTOMATCH_LOAD_ANALYSIS.md`, detailing performance issues with the Auto-Match page and recommendations for optimizations. A new document, `CONFIDENCE_CALIBRATION_SUMMARY.md`, is also added to explain the implementation of a confidence calibration system for face recognition, ensuring more accurate match probabilities. These updates enhance the project's documentation and provide insights for future improvements.
