fix(rendering): carry retail SetSurface state to detail draws

Resolve exact SetSurface blend, alpha-test, and fog state once during extraction and preserve it through recipe-10 prepared payloads, Wb/EnvCell command data, Vulkan pipelines, push constants, and both ordinary/atmospheric one-pass shaders. Preserve AP-240 Wb pure-Clip immediate opaque/A2C while EnvCell uses retail premultiplied Clip; detail-off routing remains unchanged. Correct AP-232 and register the remaining detail-off state divergence.
