* feat(map): add dual-grid autotile resolve for TileLayer
Implement Oskar Stålberg-style dual-grid: logic layer paints fill/empty,
display layer gets a half-tile offset 15-tile resolve. Document that Tiled
has no native dual-grid (Terrain/Wang Corner Set is same-grid only).

* fix(map): use ComponentRef for DualGrid config access
TileLayer::config() returns ecs::ComponentRef, not a raw pointer.

layers after resolve tests to avoid ECS draw pollution.
