Fix node click handlers to pass full data with aliases

- Ctrl/Cmd+click now passes full cytoscape node data (with aliases, isMerged)
- Right-click also passes full node data
- Added Shift+click to navigate to Add Claim / Validate page

This enables the aliases section in the detail modal to show linked
identities for merged SAME_AS nodes.
