feat: link impact summary signals to explorer with smooth scroll

[dcotelo]

Summary

• Clicking a risk signal in ImpactSummary now selects the corresponding resource in DiffExplorer and smoothly scrolls to it
• Analysis context section is now collapsed by default to keep the focus on results
• Added generateImpactStatement to risk-assessment.ts to produce plain-language summaries (e.g. "2 workloads will restart and 1 service port will change")
• DiffExplorer accepts an optional selectedResource prop and syncs its internal selection via useEffect

Changes

• analysis/page.tsx: added selectedResource state, explorerRef, and handleSelectResourceFromSummary handler; wires onSelectResource into ImpactSummaryComponent
• ImpactSummary.tsx: threads onSelectResource callback down through Section and individual signal rows
• DiffExplorer.tsx: new selectedResource prop with effect to sync external selection
• risk-assessment.ts: new generateImpactStatement utility function
