Dante 19fff29204 test: backfill e2e coverage gaps for toolkit widgets, minimap, mask editor, painter (#11183)
## Summary

Backfills missing e2e test coverage identified in the [FixIt
Burndown](https://www.notion.so/comfy-org/FixIt-Burndown-32e6d73d365080609a81cdc9bc884460)
audit. Adds 39 new behavioral tests across 5 spec files with zero
test-code overlap.

## Changes

- **What**: New e2e specs for Image Crop (6 tests) and Curve Widget (6
tests). Deepened coverage for Minimap (+6), Mask Editor (+10), Painter
(+11).
- **New fixtures**: `curve_widget.json`, updated
`image_crop_widget.json`

## Test Inventory

| Spec | New tests | Coverage area |
|---|---|---|
| `imageCrop.spec.ts` | 6 | Empty state, bounding box inputs, ratio
selector/presets, lock toggle, programmatic value update |
| `curveWidget.spec.ts` | 6 | SVG render, click-to-add point,
drag-to-reshape, Ctrl+click remove, interpolation mode switch, min-2
guard |
| `minimap.spec.ts` | +6 | Click-to-pan, drag-to-pan, zoom viewport
shrink, node count changes, workflow reload, pan state reflection |
| `maskEditor.spec.ts` | +10 | Brush drawing, undo/redo, clear, cancel,
invert, Ctrl+Z, tool panel/switching, brush settings, save with mock,
eraser |
| `painter.spec.ts` | +11 | Clear, eraser, control visibility toggle,
brush size slider, stroke width comparison, canvas dimensions,
background color, multi-stroke accumulate, color picker, opacity,
partial erase |

## Review Focus

- Mask editor tests use `.maskEditor_toolPanelContainer` class selectors
— may need test-id hardening later
- Painter slider interaction tests could be flaky if slider layout
changes
- All canvas pixel-count assertions use `expect.poll()` with timeouts
for reliability

## Test plan
- [ ] CI passes all new/modified specs
- [ ] No duplicate coverage with existing tests (verified via grep
before writing)
- [ ] No `waitForTimeout` usage (confirmed)
