Detailed Description

Reassigns the rain gage of many subcatchments as ONE undo step.

Carries parallel arrays rather than pushing a command per subcatchment, following the mesh::pushCellParamEdits idiom: a bulk spatial assignment is one user action and should cost one Ctrl+Z.

Rows already holding the target gage are filtered out by the factory below, so redo() only touches what actually changes.

Everything is keyed by NAME, never by index — gage or subcatchment deletion re-packs engine indices, and this command may be undone long after that has happened.
