Add VIO FC Status monitoring page and enhance server inventory filtering

- Introduced `Storage/VIO.php` for monitoring VIO Fibre Channel status with client balancing checks and table sorting.
- Updated `/include/en.php` and `/include/fr.php` to include new translations for ServiceNow and VIO-related navigation elements.
- Improved SQL query and filtering logic in `/X/Inventory.php` to exclude VIO entries and add XenSam version data.
- Enhanced `/reports/heartbeat.php` with a new mechanism for handling server heartbeat status, allowing better granularity and readability.
