refactor(understand): one reading of units, plan copies, scale and rooms
Groups U and N were built side by side, so the takeoffs carried narrow stand-ins for what group U reads properly. On main they read through U: - describe.drawing_units is the one call every reader makes (kept records, labelled room faces as evidence); describe, scale_check and the takeoffs all use it. Without the room faces, a layout that declares inches over millimetres can tie three ways and fall to the header. - layout_tags takes its plan copies from describe.prepare, room_regions its rooms from describe.find_rooms, and pipe_rows its scale from scale_check, per-room groups included. scale_stand_in and the takeoff's own unit bands and cluster grid are gone. - test_understand_one_reading pins the agreement: one unit, one plan copy, one verdict and one set of rooms per drawing, across drawing_understand, drawing_scale_check and the two takeoffs.
