Refactored several files to improve code clarity, error handling, and data integrity. Introduced type safety improvements, streamlined OpenAPI model integration, adjusted configuration settings, and enhanced QR code handling logic. Also updated scripts and tsconfig settings to temporarily bypass strict checks during development.
