fix(3d): restore complete SCADA scene context

The scene previously returned early when realtime rows were absent and selected map-tier assets for network mode, hiding SCADA markers and station interiors and floors.

Use SCADA timestamps as valid frames, render node-aligned monitor markers, and pin the full network context in the manifest regression test. Keep the timeline close action inside its drag header.
