/**
 * Validate Access Token DTO
 *
 * Used for validating JWT access tokens and decoding their payload.
 *
 * Security:
 * - Token length validated (prevents DoS)
 * - JWT tokens can be long, but we validate input length
 * - Token is validated in service layer for format, signature, and expiration
 *
 * @example
 * ```typescript
 * const result = await authService.validateAccessToken({
 *   accessToken: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
 * });
 * ```

     * Validation:
     * - Must be a string
     * - Min 10 characters (minimum valid JWT length)
     * - Max 2048 characters (prevents DoS, typical JWT is 200-500 chars)
     *
     * Note: Token format, signature, and expiration validated in service layer
