Dimension inputs now work for all work area types

Structure, site, and elevation areas now use linked feet-and-inches inputs with automatic area calculation.

Bug Fixes

Previously, only room work areas supported linked dimension inputs (width, length, height). Structure, site, and elevation areas required manual area entry, breaking the estimate formula resolver for those targets.

Now all work area types support the same dimension inputs:

  • Structure & Site: width × length = area
  • Elevation: height × length = wall area
  • Room: width × length × height = volume

Area is automatically calculated from dimensions instead of requiring manual entry. Elevation opening measurements are also now displayed in square feet for consistency.
