nostrverse: fix rotation editor euler decomposition and tilemap z-fighting

to_euler(YXZ) returns (Y, X, Z) but the rotation editor and drag-snap
code destructured as (_, y, _), reading the X angle instead of Y.
Also bump the tilemap Y offset from 0.001 to 0.01 so depth buffer
can distinguish it from the grid plane.
