Each command operates on one non-owning TransectProvider*. Commands are pushed onto the dialog's QUndoStack so a single Cmd-Z unwinds across the list, the property tree, the station-elevation grid, and the chart in lock-step (every view subscribes to the provider's signals and re-renders on apply).

Chart-drag batching follows the timeseries Phase 6.7.3.5 pattern:

• mouse press → capture the original (station, elevation)
• mouse move → setPointLive (no undo push, no monotonicity break)
• mouse release → push one MoveStationPointCommand whose redo() is a no-op (state already current) and whose undo() restores the original position.

Each command emits no UI work directly — the provider's signals drive the redraw. That keeps the redo / undo paths perfectly symmetric and lets tests assert correctness without needing the dialog at all.
