feat(view): solplate in the 3D model (2단계): wedges from the drawing's A, B, S; read the solplate table from DXF

Each bearing gets a solplate wedge: tapered along the 교축 with T1 on the 시점 side, underside at the bearing top (block
top + h3). A, B come from the drawing's ELEVATION table, S and T1/T2 from the SOLPLATE table (NO, S(%), L, W, T, T1, T2),
read by position. The 공통 규칙 (T 30, margin 100, h3 181) feed the plan; changing them regenerates the piers. A new
"솔플레이트" part can be shown or hidden. A solplate table is read only when its S values are found; a missing S is reported.
Also commits the option-1 test change (drawing EL.X minus Excel z).
