Merge origin/master with current Pierzainer development

Preserve local abutment, cast-in-place rebar and compact header features alongside remote drawing, ground-link and quantity workspaces. Adapt drawing and takeoff consumers to generated solplate plans, retain current P1 regression coverage, and resolve bearing-detail annotation collisions.

Validation: 122 test files / 975 tests passed; production build passed; 10 browser integration checks passed.
