 * 1. Two flows based on platform:
 *    - platform = 'web': Document upload first, then password reset
 *    - platform = 'app': Password reset only
 * 2. Document upload with camera/gallery selection
 * 3. Password and confirm password input fields
 * 4. Real-time password validation with visual feedback
 * 5. Password visibility toggles
 * 6. Password strength requirements display
 * 7. Integration with Redux for onboarding status
 * 8. API integration for document upload and password change
 * 
 * Password Requirements:
 * - At least 8 characters
 * - One uppercase letter
 * - One lowercase letter
 * - One number
 * - One special character
 * - Passwords must match
