Complete phase 3 W1 acceptance and close T16 findings

Fix Navara model display tint, overlay ordering, follow gestures and resource cleanup.
Reduce repeated aircraft work and correct fixture enrichment responses.
Strengthen dev/preview QA, preserve failure history and document verified W1 results.

Validation: 7171 ordinary tests pass, one Windows-only skip; 15 allocation probes;
37 W1 acceptance steps; contracts, shell, four performance gates; 18 identical
Cesium baseline PNGs. Known pre-existing CCTV and live-source limits are recorded.
