Fix alpha-tested blend depth writes

Browse source 
Add paired depth-write variants for all five blended SetSurface families in ordinary and atmospheric Wb pipeline sets at both sample counts and in EnvCell. Select them only from the carried AlphaTestEnabled state, retain pure-Clip and Translucent override behavior, and cover disposal plus partial-construction rollback.

Correct the three stale depth oracles and the AP register count/temporary AP-232 overclaim.

Required restored mutations and first discriminating failures:

1. Wb StraightAlpha+Clip collapsed to depth-off: WalkStaticStreamPopulatorTests.ImmediateBuildingDetail_UsesExactResolvedSetSurfaceState failed at line 1278; expected wb-mesh-alpha-depth-write-1x, binds were wb-mesh-alpha-1x.

2. EnvCell raw Additive+Clip collapsed to depth-off: EnvCellAlphaDrawSourceTests.DetailOn_EveryEnvCellFamilyDrawsOnceInPlaceWithAuthoredOpacity failed at line 132; expected envcell-raw-additive-depth-write, actual envcell-raw-additive.

3. EnvCell non-Clip raw Additive forced depth-on: the same production transcript failed at line 132; first row expected envcell-raw-additive, actual envcell-raw-additive-depth-write.

4. Late Translucent|Clip override forced alpha-test/depth-on: the same production transcript failed at line 132; expected envcell-alpha, actual envcell-alpha-depth-write.
