fix: Use historical records to average disk usage for extra disk alerts (#1801)

- Introduced a new test file `alerts_disk_test.go` to validate the behavior of disk alerts using historical data for extra filesystems.
- Enhanced the `HandleSystemAlerts` function to correctly calculate disk usage for extra filesystems based on historical records.
- Updated the `SystemAlertStats` struct to include `ExtraFs` for tracking additional filesystem statistics.
