feat(bearing): section and solplate detail drawings with the drawing values overlaid (승인 2026-10-26)

- view/bearing-section-svg.ts: the pair's elevation — blocks (일체: one stepped
  outline), mortar, bearing body and solplate per bearing from the model; the
  drawing heights overlaid dashed. EL.X at the mortar top, E = h1 + h2 + h3 + h4.
- view/solplate-svg.ts: per bearing, the plan L × W and the taper T1 · T2
  (S %), with the drawing values dashed.
- ② bearing card: section figure and the two solplate figures under the plan.
