* Widget that displays security resources and implementation guides
*
* This component provides security practitioners with relevant resources,
* implementation guides, and best practices to help implement appropriate
* security controls for the selected security levels. It bridges the gap
* between security requirements and practical implementation.
*
* ## Features
* - Dynamic resource filtering based on security levels
* - Categorized display of resources by CIA component
* - Support for limiting displayed resources
* - Top resources filtering for focused guidance
* - Loading and error states
* - Accessible and responsive design
*
* ## Business Perspective
*
* This widget accelerates security implementation by providing practitioners
* with immediately actionable guidance, reducing research time and ensuring
* best practices are followed. It improves security ROI by helping teams
* implement controls correctly the first time. 📚
*
* @component
*
* @example
* ```tsx
* // Basic usage with uniform security levels
* <SecurityResourcesWidget
* availabilityLevel="Moderate"
* integrityLevel="Moderate"
* confidentialityLevel="Moderate"
* />
*
* // Advanced usage with custom configuration
* <SecurityResourcesWidget
* availabilityLevel="High"
* integrityLevel="Very High"
* confidentialityLevel="Moderate"
* maxItems={12}
* showTopResourcesOnly={true}
* className="border-2 border-gray-200 p-md"
* testId="main-security-resources"
