Detailed Description

Per-project flow-units state + label helpers.

Each SWMMVisProjectWindow owns one instance and writes/reads the FLOW_UNITS option through it. The class also exposes a delegating facade via UnitSystem::instance() — a singleton whose accessors forward to whichever per-project instance is currently active (set on MDI tab switch).

Existing callsites like UnitSystem::instance()->depthLabel() keep working unchanged; the value reflects the focused project, not a global setting.
