## Summary
Implemented E2E test coverage for Levels 6-12 of the Painter Widget
## Changes
Adds the following coverage to complete the test plan:
Level 6 - Input image connection (3 tests, @slow):
- Width/height/bg-color controls hide when input is linked
- Canvas resizes to match input image dimensions after execution
- Drawing over input image produces canvas content
Level 7 - Clear on empty canvas is harmless
Level 8 - Unchanged canvas does not re-upload on second serialization
Level 9 - Settings persistence:
- Tool selection saved to node.properties.painterTool
- Brush size change saved to node.properties.painterBrushSize
Level 10 - Compact layout collapses to grid-cols-1 when node width <
350px
Level 12 - Rapid drawing accumulates all strokes (checks 3 y-positions)
Supporting changes:
- Add data-testid="painter-controls" to controls grid in
WidgetPainter.vue (needed for compact mode class assertion)
- Add browser_tests/assets/widgets/painter_with_input.json workflow
fixture (LoadImage connected to Painter input slot 0)

> [!NOTE]
> **Low Risk**
> Mostly adds/adjusts Playwright and unit test coverage; the only
runtime change is wrapping pointer-capture calls in `try/catch`, which
is low-risk but touches input-handling paths.
>
> **Overview**
> Completes and expands Painter widget browser test coverage, including
new scenarios for clearing an empty canvas, preventing redundant uploads
when serializing an unchanged canvas, persisting tool/brush-size
settings to node properties, compact layout behavior, multi-stroke
accumulation checks, and an input-image-connected workflow (new
`painter_with_input.json`) with execution/resizing/draw-over-image
assertions.
>
> Hardens `usePainter` pointer handling by tolerating
`setPointerCapture`/`releasePointerCapture` failures (e.g., synthetic
events), with corresponding unit tests updated/added to validate the
behavior and serialization expectations.
