/**
 * Custom hook for managing CIA triad security levels
 *
 * ## Business Perspective
 *
 * Provides unified state management for security officers to configure
 * organizational security posture across all three CIA components. This
 * centralization ensures consistent security level handling and simplifies
 * state management across the application. 🔒
 *
 * ## Technical Perspective
 *
 * Extracts common security level state management pattern found in 8+ widgets,
 * reducing code duplication by ~20% and ensuring consistent behavior. Uses
 * React hooks best practices with proper memoization for optimal performance.
 *
 * @param initialLevels - Initial security levels (defaults to 'Moderate' for all components)
 * @returns Security level state and update functions
 *
 * @example
 * ```tsx
 * // Basic usage with defaults
 * const { levels, setLevel, getLevel } = useSecurityLevelState();
 *
 * // Update a level
 * setLevel('availability', 'High');
 *
 * // Get a level
 * const currentLevel = getLevel('integrity');
 *
 * // Initialize with custom levels
 * const { levels } = useSecurityLevelState({
 *   availability: 'High',
 *   integrity: 'Moderate',
 *   confidentiality: 'Very High'
 * });
 *
 * // Reset all levels
 * resetLevels('Low');
 * ```
