Highlight same-net traces on hover

[ChandraDvitiyah]

Summary

• add hover handling for schematic traces using existing rendered data-schematic-trace-id metadata
• group schematic traces by their source trace connectivity key so every same-net segment highlights together
• restore original trace strokes on pointer out/leave and skip invisible hit-target paths
