fix(inbounds): hide node UI when no enabled node exists

The Deploy-to selector, node column, node stat row, and node filter all
appeared whenever a node row existed in the DB. Local-only deployments
with no nodes (or only disabled nodes) saw a dropdown that only had
"Local Panel" and a filter that did nothing.

useNodeList now exposes hasActive (any node with enable === true).
Inbounds form and list gate node UI on hasActive instead of map size.
