Arrow-key canvas panning on Graph and Flows#23

Conversation
Arrows pan the active canvas 5px per keydown (25px with Shift) via a new
{type:'pan'} resolver action and panBy(dx,dy) on both view handles; OS
key-repeat gives continuous scrolling. Dict, editable targets, and
ctrl/meta/alt chords keep their native arrow behavior.
5px felt too slow for practical scrolling; PAN_STEP/PAN_STEP_FAST move to 10/50 (ratio unchanged at 5x). Docs and tests updated to match.

Summary
resolveShortcutkeymap (same guard slot as?, since Shift is the step multiplier); routed to a newpanBy(dx, dy)onGraphViewHandleandFlowsViewHandle. The flow SVG reuses its drag-pan screen→viewBox conversion.What this solves
The DG and DFD canvases were mouse-only for scrolling; keyboard users had no way to nudge the viewport.
