## Summary
Fix the bottom-right graph canvas toolbar (zoom controls, fit-to-view,
minimap toggle) not being visible on mobile devices in normal graph
mode.
## Problem
PrimeVue applies `overflow: hidden` to all `.p-splitterpanel` elements
by default. The `GraphCanvasMenu` component is absolutely positioned
(`right-0 bottom-0`) inside the `graph-canvas-panel` SplitterPanel. On
mobile viewports, the panel's bounding box can be smaller than the full
canvas area, causing the toolbar to be clipped by the `overflow:
hidden`.
## Solution
Add `overflow-visible` to the `graph-canvas-panel` SplitterPanel class
to override PrimeVue's default `overflow: hidden`. This allows the
absolutely-positioned toolbar (and minimap) to remain visible regardless
of viewport size.
