feat: Implement ID card and selfie verification process using Azure OCR and Face API

- Added AzureOCRService to handle ID card processing and face verification.
- Integrated image picker for uploading ID cards and selfies.
- Updated registration form to include ID card upload and selfie verification sections.
- Enhanced validation for extracted OCR data based on user role (officer or civilian).
- Added liveness check functionality for selfie verification.
- Improved user interface for image upload and verification status messages.
