feat(ui): Complete Sprint 3500.0004.0002 - UI Components + Visualization
Sprint 3500.0004.0002 - 8/8 tasks completed: T1: ProofLedgerViewComponent - Merkle tree visualization, DSSE signatures T2: UnknownsQueueComponent - HOT/WARM/COLD bands, bulk actions T3: ReachabilityExplainWidget - Canvas call graph, zoom/pan, export T4: ScoreComparisonComponent - Side-by-side, timeline, VEX impact T5: ProofReplayDashboardComponent - Progress tracking, drift detection T6: API services - score.client.ts, replay.client.ts with mock/HTTP T7: Accessibility - FocusTrap, LiveRegion, KeyNav directives (WCAG 2.1 AA) T8: Component tests - Full test suites for all components All components use Angular v17 signals, OnPush change detection, and injection tokens for API abstraction.
