fix(rendering): port retail shared alpha list

Browse source 
Queue translucent world GfxObj batches and scene particles in one stable far-to-near stream using transformed DAT sort centers, then drain it at retail's landscape and final-world boundaries. Preserve authored blend, cull, lighting, opacity, and adjacent-only batching so particles behind lifestones are composited through the crystal instead of overpainting it.

Release build succeeds and all 5,914 tests pass with five intentional skips.
