The metric/imperial preference was already honored by every length input, but two area surfaces were still hardcoded to m²: - the "Load build" import dialog's Floor area stat - the auto-generated default names for zones, slabs, and ceilings (e.g. "Zone (12.3m²)"), which are live display fallbacks Both now convert value + label to the active unit. Adds shared squareMetersToAreaUnit / getAreaUnitLabel / formatAreaLabel helpers to lib/measurements (with tests) and routes the site-panel Area readout through them, replacing an inline 10.7639 magic constant.
