Add API logging functionality and enhance scheduler service

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.
