/**
 * DTO for resending verification code
 *
 * Used to resend email/SMS verification codes during challenges:
 * - Email verification (VERIFY_EMAIL)
 * - Phone verification (VERIFY_PHONE)
 * - MFA verification (MFA_REQUIRED with SMS/Email method)
 *
 * Security:
 * - Session token length limited (prevents DoS)
 * - Rate limiting enforced in service layer
 *
 * @example
 * ```typescript
 * const result = await authService.resendCode({
 *   session: 'challenge-session-token'
 * });
 * // Returns: { destination: 'u***r@example.com' }
 * ```

     * - Must be a valid UUID v4 format
     * - Generated using randomUUID() in challenge service
     * - Matches DB constraint: varchar(255) but UUID format enforced
     *
     * Sanitization:
     * - Trimmed
     * - Lowercased for consistency
     *
     * @example "a21b654c-2746-4168-acee-c175083a65cd"
