Mirrors CurveEditChartView but with pattern-shape semantics:

• Vertical drag → change the factor at the picked slot (Y-only; X is categorical so the slot index is fixed during a Y-drag).
• Horizontal drag → reorder slots: dragging a vertex across an adjacent slot's centre triggers a swap (provider-mediated, atomic, undoable). Multi-step horizontal drags chain swaps so the picked slot can travel several positions in one gesture.

EditMode toggles which axis is active during a left-button drag:

• None — base Select/Pan/Zoom only.
• EditPoints — vertical drag = factor edit; horizontal drag = swap.

MVC contract: all mutations route through PatternProvider. The chart view, factor-table view, and any property pane subscribe to the provider's factorChanged / factorsChanged signals so each frame of a drag is mirrored everywhere. Drag completion pushes a single QUndoCommand so a Cmd-Z reverts the whole gesture.
