Add hazard spikes on the tree tops (grey spikes from the tileset atlas)

The two new spikes were painted as tiles in TerrainBase, but tileset collision can only make a solid wall, not a damaging hazard. Replaced them with a real spikes_grey prefab that uses the same atlas tile (8,3) plus hazard.gd, and erases the placeholder tile on ready. Also includes the level edits made in the editor (top-left terrain rework).
