Replace em-dash and ad-hoc loaders with the shared job-tray spinner
for deploy templates, host/swarm/tunnels/events, health latency,
container stats/logs/processes, and registry/volume browsers.
Always show a containers action bar (start/stop/restart/pause/resume/kill/
recreate/remove/prune) driven by row selection via typed bulk RPC. Rebuild
the container Networking tab into a join/leave network manager with aliases
and optional static IPs, plus a clearer ports table.
