Normalize spacing before units across all calc sheets
Plain units already get a gap from the source whitespace, so drop the leading space inside the string; keep it only on superscripted units (in^2, in^3, in^4, ft^2). Also fix the generated concrete-beam figure labels. Regenerate all affected PDFs.
