Refactor network API calls to use centralized authentication context and improve cache handling
- Removed redundant getApiToken function and replaced its usage with getAuthContext in network-api.js, network-events.js, and network-init.js. - Updated cache handling in network-events.js and network-init.js to use CACHE_KEYS constants for better maintainability. - Introduced cache.js for centralized cache management functions and constants, including cache initialization and retrieval. - Added app-init.js for application lifecycle management, including cache orchestration and initialization checks. - Created app_config.php to securely fetch API token and GraphQL port from configuration. - Improved error handling and logging throughout the codebase for better debugging and maintenance.
