feat(verification): implement QR verification system with modular architecture and CI fixes

- added QR, credential, and blockchain verification flows
- refactored app into blueprints and services
- improved UI and credential handling
- updated tests and add smoke coverage
- aligned docker and CI workflows
- added missing runtime dependencies (pyotp, PyPDF2)
- resolved CI pytest bootstrap failures
