fix: show containers in network config view

NetworkList does not populate the Containers field in the response.
When viewing a network's config, the Containers section always showed
'none' regardless of how many containers were attached.

Use NetworkInspect to fetch full network details including connected
containers when rendering the config panel.

Fixes #752
