Issue:
The topology prefix handling was previously inconsistent. And this impacting the edgeShark handling from TopoViewer.

Fix Strategy:
Update the environment.json file by enriching its EnvCyTopoJsonBytes field using live topology data from the active Cytoscape (cy) instance. This enrichment process correctly computes the prefix using production-grade logic and ensures that each edge contains accurate clabSourceLongName and clabTargetLongName values. The prefix logic now safely handles invalid or missing values, avoiding unintended "null" strings.

• Prefix handling in topology: The edgeShark handler reads link data from the updated environment.json. Since this file is refreshed using cy.elements().jsons() enriched by the prefix-aware logic, it reflects the correct topology state. This ensures that all node and edge names — including those with optional prefixes — are consistent and valid for downstream processing.
