feat(rebar,view): coping end height h1, taper h2 and Level width as inputs on ② (1단계)

The three values are inputs on the coping card, with the P1 values (1000 · 1500 · 2100) when absent, and they are tracked
like the other shape inputs. The geometry and the coping rebar read them from one CopingGeom: the U heights follow the
closed form (h1 − 2c) + h2·min(x_s, x_L0)/x_L0, which reproduces the P1 values. The side rows are assumed to keep their
position relative to the Level underside (명세 확인 필요). P1 results are unchanged; the full suite passes.
