feat(view): bearing reference tables on ② (drawing values, read-only, not used in the model)

The P1 상세도 ELEVATION TABLE and 솔플레이트 TABLE are shown on the bearing card. The model does not use them (Q16). The
ELEVATION table compares the drawing's coping top (EL.X − E) with the model's coping top; the difference is a constant
0.211 m on all ten bearings. The solplate table checks T1 and T2 against T ± L·|S|/2 with the 공통 규칙 T = 30 mm; all
rows match. Tests check E = h1+h2+h3+h4, L and W, the T1/T2 rule, and the constant offset.
