Alexander Brown db1257fdb3 test: migrate 8 hard-case component tests from VTU to VTL (Phase 3) (#10493)
## Summary

Phase 3 of the VTL migration: migrate 8 hard-case component tests from
@vue/test-utils to @testing-library/vue (68 tests).

Stacked on #10490.

## Changes

- **What**: Migrate SignInForm, CurrentUserButton, NodeSearchBoxPopover,
BaseThumbnail, JobAssetsList, SelectionToolbox, QueueOverlayExpanded,
PackVersionSelectorPopover from VTU to VTL
- **`wrapper.vm` elimination**: 13 instances across 4 files (5 in
SignInForm, 3 in CurrentUserButton, 3 in PackVersionSelectorPopover, 2
in BaseThumbnail) replaced with user interactions or removed
- **`vm.$emit()` on stubs**: Interactive stubs with `setup(_, { emit })`
expose buttons or closure-based emit functions (QueueOverlayExpanded,
NodeSearchBoxPopover, JobAssetsList)
- **Removed**: 6 change-detector/redundant tests, 3 `@ts-expect-error`
annotations, `PackVersionSelectorVM` interface, `getVM` helper
- **BaseThumbnail**: Removed `useEventListener` mock — real event
handler attaches, `fireEvent.error(img)` triggers error state

## Review Focus

- Interactive stub patterns: `JobAssetsListStub` and `NodeSearchBoxStub`
use closure-based emit functions to trigger parent event handlers
without `vm.$emit`
- SignInForm form submission test fills PrimeVue Form fields via
`userEvent.type` and submits via button click (replaces `vm.onSubmit()`
direct call)
- CurrentUserButton Popover stub tracks open/close state reactively
- JobAssetsList: file-level `eslint-disable` for
`no-container`/`no-node-access`/`prefer-user-event` since stubs lack
ARIA roles and hover tests need `fireEvent`
