feat: active config snapshot, composite StatusDot with tooltip

Part 1 — Config snapshot:
- V8 migration adds resolved_config JSONB to deployments table
- DeploymentExecutor saves the full resolved config at deploy time
- Deployment record includes resolvedConfig for auditability

Part 2 — Composite health StatusDot:
- CatalogController computes composite health from deployment status +
  agent health (green only when RUNNING AND agent live)
- CatalogApp includes healthTooltip (e.g. "Deployment: RUNNING,
  Agents: live (1 connected)")
- StatusDot added to app detail header with deployment status Badge
- StatusDot added to deployment table rows
- Sidebar passes composite health + tooltip through to tree nodes
