New FederationSettingsDialog edits the federation-wide unit and the
FederatedFalseOrigin (XYZ + Z-rotation in that unit). On Ok it calls
Federation::setConfig + setFederatedFalseOrigin, which fire the
granular Federation signals MainWindow listens to → viewport
recomposes immediately.
Reachable from File > Federation Settings. Unit picker is a fixed
combobox of common length units (metres / mm / cm / km / ft / in /
yd / mi); each item carries (prefix, name) in itemData so saving
round-trips correctly. Per-model ModelTransformation editor still
to come — that's a per-model dialog reachable from the model entry,
not the federation-wide settings.
