Phases 4-6: Complete Central UI — Admin, Design, Deployment, and Operations pages
Phase 4 — Operator/Admin UI: - Sites, DataConnections, Areas (hierarchical), API Keys (auto-generated) CRUD - Health Dashboard (live refresh, per-site metrics from CentralHealthAggregator) - Instance list with filtering/staleness/lifecycle actions - Deployment status tracking with auto-refresh Phase 5 — Authoring UI: - Template authoring with inheritance tree, tabs (attrs/alarms/scripts/compositions) - Lock indicators, on-demand validation, collision detection - Shared scripts with syntax check - External systems, DB connections, notification lists, Inbound API methods Phase 6 — Deployment Operations UI: - Staleness indicators, validation gating - Debug view (instance selection, attribute/alarm live tables) - Site event log viewer (filters, keyword search, keyset pagination) - Parked message management, Audit log viewer with JSON state Shared components: DataTable, ConfirmDialog, ToastNotification, LoadingSpinner, TimestampDisplay 623 tests pass, zero warnings. All Bootstrap 5, clean corporate design.
