mesh: one transfinite interpolation for mapped hex and mesh.block; stable oracle report (#52)

* mesh: one transfinite interpolation for mapped hex and mesh.block; stable oracle report mesh.block's lattice is now built from the structured hex mesher's transfinite code: faces by quad::transfinite_grid, the interior by the new quad::transfinite_volume (Gordon-Thiel, blended by the block's graded parameters), which hex::mapped now calls too. 2D patches are the transfinite_grid of their sides. Edge curves return their corners exactly. Oracle: a zero-reference quantity (rounding noise) keeps its absolute tolerance as its fixture band, and docs/oracle.md shows such noise and relative errors inside the fixture band as bounds, so the report no longer changes with the order of floating-point operations (it failed the 'docs/oracle.md is current' check on main after #50). Scordelis-Lo moved by 1.4e-9 relative (an ill-conditioned thin shell of solids: sub-ulp node changes) and is re-blessed.

Straight edges also return their corners exactly.
