Read QA drawing evidence through the globe contract

Port the layer probes in twenty-six browser scripts to engine primitive
lists, drawn rows and layer diagnostics. Preserve Cesium as the reference
and keep the supported Navara paths on the same observations. This
changes QA observation only, with no application behaviour change.

Review the interrupted infrastructure group and retain its readiness,
drape, selection, label and floor checks. Match both installation outline
buffers. Frame each CCTV city before reading its visible coverage. Read
Radio colours and selected identities from actual mover writes. Retain
transit's GPU upload budgets using engine-owned line primitives rather
than substituting rebuild counts. Keep native inspection where a check
specifically measures GPU uploads, loaded meshes or ground readiness.

The preceding combined B/C commit owns all shared manifests, docs,
locale catalogs and the coupling baseline; this commit changes only its
own twenty-six QA scripts. Coupling remains unchanged at 344 Cesium
renderer lines, 1294 Navara renderer lines, 9 Cesium import files, 1026
viewer lines, 2 Navara kind checks, 0 engine sniff calls, 9 extension
reads, 1 ground pass, 3 SDK loads, 4 screen-handler files and 42 engine-name
lines.

The full unit suite and the boundary, format and coupling checks pass.
Browser validation remains to be run.

The military-names driver exercises installation-polish; the transit
driver exercises transit-scenes. Use only the keyless server. Cases that
require photoreal tiles or unavailable providers remain unverified.
