Add monitoring features and alert configurations

- Introduced new system metrics tracking with the ability to save and retrieve metrics such as CPU usage, memory usage, and network latency. - Added alert configuration functionality, allowing users to set thresholds for metrics and receive notifications via email or chat. - Updated the sidebar component to include a new "Monitorar SGSE" card for real-time system monitoring. - Enhanced the package dependencies with `papaparse` and `svelte-chartjs` for improved data handling and charting capabilities. - Updated the schema to support new tables for system metrics and alert configurations.
