[vivanovbc]

Changes

• Card: Verification Info: As an Industry Reporter, I want to fill out the SFO verification form cas-reporting#199 (comment)
• Updated ReportVerification model to include new fields and modify existing ones
• Modified BaseReportVerificationSchema to align with new model changes
• Updated verificationSchema and verificationUiSchema in frontend to reflect new requirements
• Adjusted VerificationForm component to handle new form structure

Acceptance Criteria

• "Site visited" options (Facility X, Other, None) include required fields for threats to independence and verification conclusion
• Facility X and Other options include "Type of site visit" field
• Other option shows additional fields for site name and geographic location
• Backend model and schema align with frontend changes
• Form validation works correctly for all new fields and dependencies

Test Plan

1. Run migrations and start the application
2. Navigate to the Verification form
3. Test each "Site visited" option:
   • Verify required fields appear for each option
   • Ensure conditional fields show/hide appropriately
4. Submit the form with various combinations of inputs
5. Verify data is correctly saved to the database
6. Check API responses include all new fields
