Erik 6b0472ee32 fix(rendering): port retail shared alpha list
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.

// #193 (regression from #188, 2026-07-09): WbDrawDispatcher's InstanceGroup holds
// seven per-instance parallel lists — Matrices, LocalSortCenters, Slots,
// LightSets, IndoorFlags, Opacities, SelectionLighting — appended in lockstep
// (one entry per drawn instance) every frame. The
// per-frame reset must clear ALL of them. #188 added Opacities but left it out of
// the inline clear loop, so it grew one float per instance per frame forever; as
// List<float>'s backing array doubled it produced ~128 MB / ~512 MB LOH float[]
// arrays and leaked ~1 GB/min -> OOM after ~50 min of play. This test pins that
// every parallel list is reset, so a newly-added list can't silently drift again.
