 * Error thrown when input data (DTO - Data Transfer Object) fails validation against the defined Zod schema.
 * This error indicates that the client sent invalid or malformed data that doesn't match the API's expected format.
 * Extends APIError with HTTP 403 status code to indicate a client-side input validation error.
 *
 * @example
 * ```typescript
 * // API expects { name: string, age: number }
 * // Client sends { name: "John", age: "invalid" }
 * // Results in InvalidDTOError being thrown
 *
 * try {
 *   await validateDTO(inputData)
 * } catch (error) {
 *   if (error instanceof InvalidDTOError) {
 *     console.log('Validation errors:', error.zodError?.issues)
 *   }
 * }
 * ```
