Pull request overview

This PR addresses Issue #1124 in the SSVC calculator UI by adjusting the stacking order of the zoom/scale slider so it can be interacted with (not covered by the graph layer) when using the Coordinator Triage model.

Changes:

• Added a higher z-index to the #zoomcontrol container to ensure the vertical range input remains clickable/draggable above the rendered graph.

Comments suppressed due to low confidence (1)

• alt is not a valid/accessibility-relevant attribute for <input type="range">. Use an accessible name (e.g., aria-label) so screen readers can announce the control consistently.

	     style="z-index:100">
	  <div class="d-none">&#128269;</div>
	  <input type="range" orient="vertical" alt="Zoom Graph"
		 max="100" min="0" value="100" title="Zoom Graph"
		 onchange="svgzoom(this)">

Also resolves the issue in #1198 - where there is a collision between div names if the strings are similar like "Supplier Cardinality" vs "Supplier Engagement"
