Remove test.php and enhance null safety and sorting across components

- Deleted `test.php` as it was no longer in use.
- Enhanced null safety checks in `Inventory.php`, `StdOut-detail.php`, `Backups.php`, and `SwitchsSAN.php` to prevent potential warnings.
- Refactored `SwitchsSAN.php` to improve sorting logic for ports based on errors, vFabric, and Port ID.
- Added seasonal snow effect script in `all.php` with toggle functionality for user engagement.
- Updated navigation bar (`navbar.html`) to include a new VIO page link.
- Introduced a new `VIO.php` page to display VIO monitoring details with table export and sorting features.
