- Fix environment variable type checking for Veriff and ComplyAdvantage providers
- Add required 'message' field to notification service calls
- Fix risk assessment type mismatches
- Update audit logging to use 'verified' action type (supported by schema)
- Resolve all TypeScript errors and unused variable warnings
- Add TypeScript ignore comments for placeholder implementations
