Add Neo4j sync status panel within the ingestion health admin dashboard: sync timestamps, outcome badge, node/relationship counts, "Force Re-sync" button with Full/Incremental toggle (PatternFly ToggleGroup), backend routes for Neo4j health status and force sync, and Neo4j sync adapter health tracking hook integration.

Tasks

From openspec/changes/ingestion-health-dashboard/tasks.md group 5 (RHIDP-15338):

• 5.1 Implement GET /api/boost/ingestion-health/neo4j route returning Neo4j sync status
• 5.2 Add Neo4j panel rendering in IngestionHealthPanel.tsx below connector cards
• 5.3 Add Neo4j panel header with "Knowledge Graph Sync" title and graph icon
• 5.4 Add sync status display (last sync timestamp, outcome badge, node count, relationship count)
• 5.5 Add "Force Re-sync" button with mode toggle (Full/Incremental)
• 5.6 Implement POST /api/boost/ingestion-health/neo4j/force-sync route with mode parameter

Specifications

• openspec/changes/ingestion-health-dashboard/specs/admin-health-ui/spec.md

Start with openspec/changes/ingestion-health-dashboard/tasks.md group 5 and specs/admin-health-ui/spec.md, then inspect IngestionHealthPanel.tsx and the existing ingestion-health implementation. Done means the Neo4j routes, panel states and controls, and sync adapter health tracking hooks satisfy tasks 5.1–5.9 and the specification.
