Introduced ApiLog model and integrated logging for scheduled tasks in the SchedulerService. Updated server.js to include request logging middleware and new API log routes. Enhanced frontend navigation by adding a link to system logs for admin users. Adjusted session check interval in App.vue for improved performance. This update improves monitoring and debugging capabilities across the application.
