Fix: topology chart deletion

[Salah-Tamer]

Description

Fixed an issue in the Network Topology view where deleting the second empty chart would cause the entire layout to collapse. The bug was caused by inconsistent handling of empty arrays in the route query parameters.

The fix ensures that route query parameters (input and af) are always maintained in the route, regardless of whether the charts are empty or not. This creates consistent behavior when managing empty charts and keeps the layout stable during deletion operations.

Implementation details:

• Modified the (pushRoute) function to always maintain query parameters
• Simplified the route update logic for more consistent behavior

How Has This Been Tested?

1. Created multiple empty charts (2 and 4) to verify consistent behavior
2. Deleted charts in different orders to ensure layout stability
3. Verified route query parameters are maintained correctly
4. Tested layout preservation with empty charts
5. Verified that both (input and af) parameters remain in the route
