Forward dismiss event from DefaultBox, wait for modal hide to prevent
element click interception in Vue 3.

Add name prop to all Multiselect components to fix invalid aria-label
attribute. vue-multiselect generates aria-label as 'name-searchbox', so
when name is empty it becomes '-searchbox' which is invalid.

- Change @vitejs/plugin-vue2 to @vitejs/plugin-vue
- Add vue → @vue/compat alias for Vue 3 compatibility mode
- Add vue/dist/vue.esm.js alias pointed to @vue/compat
- Configure template compiler with compatConfig MODE: 2
- Update build-config.shared.js vue alias to use @vue/compat

portal-vue uses Vue.extend which doesn't exist in Vue 3. This adds:
- A Vite plugin to intercept portal-vue imports and redirect to mock
- Mock portal-vue module using Vue 3's Teleport component
- bootstrap-vue ESM alias for better Vite transformation

Replace Vue 2 config (Vue.config.productionTip) with @vue/compat
configureCompat call. Suppress expected migration warnings for
Vue 2 features used in tests.

- Remove createLocalVue (not available in VTU v2)
- Return global mount options object for mount()
- Add bootstrap-vue component stubs (incompatible with Vue 3)
- Remove vue-rx and bootstrap-vue plugins (Vue 2 only)
- Update createTestRouter with catch-all route

Use $scopedSlots (Vue 2 compat API) with fallback to $slots for
passing slot props in render function. The pure Vue 3 renderSlot()
doesn't work correctly with compat mode's slot handling.

Configure shouldFailOnWarn to show Vue compat mode warnings without
failing tests. This allows migration to proceed while keeping warnings
visible for tracking progress.

Switched to createRouter/createWebHistory, added setActivePinia call, and
suppress Vue compat warnings during migration.

Created adapters that allow old Vue 2 test patterns to work without modifying
individual test files:

- vue-test-utils-adapter.ts: Transforms { global: localVue, pinia, router }
  mount options to proper VTU v2 format with plugins array
- vue-router-adapter.ts: Provides VueRouter constructor for tests using the
  old `import VueRouter from 'vue-router'` and `new VueRouter()` pattern
- helpers.js: Added .use() method to getLocalVue() for localVue.use() calls
- setup.ts: Relaxed fail-on-console to not fail on Vue compat warnings

These adapters are a bridge during migration - tests can be updated to use
proper Vue 3 patterns incrementally while the adapters keep things working.

- Add missing vi import in PersistentTaskProgressMonitorAlert test
- Remove duplicate jest helper imports (now using vitest helpers)
- Update VueRouter usage to v4 pattern with createTestRouter()
- Change wrapper.destroy() to wrapper.unmount() (VTU v2 API)
- Change propsData to props in mount options (VTU v2 API)

Vue Router 4 deprecates the next() callback in favor of returning
values from navigation guards. beforeRouteEnter is the one exception
(still needs next(vm => ...)) since the component instance isn't
available yet — DataManager.vue is left as-is for that reason.

Uses the existing createConfiguredApp-based mounting utility instead
of the Vue 2 Vue.extend() + new constructor().$mount() pattern.

Replace vue2-teleport with native Vue 3 Teleport in HeadlessMultiselect,
and drop vue-class-component and vue-property-decorator which have no
remaining imports in the codebase.

- Remove duplicate v-bind attributes in storage overview charts
- Move v-for key to <template> tag in GTable (Vue 3 requirement)
- Replace vue-router/composables imports with vue-router (VR4 path)
- Remove Vue.set() usage, use direct property assignment (Vue 3 Proxy)
- Update eslint wrapper for flat config (eslint.config.mjs)

GTable: move :key to <template v-for> per Vue 3 requirement.
FormData: remove duplicate v-model:workflow-tab and convert remaining
:formats-visible.sync to v-model:formats-visible.

Also regenerate pnpm-lock.yaml after package.json conflicts during
rebase onto upstream/dev.

setup.ts referenced an undefined `Vue` global to register the
g-tooltip mock directive. In Vue 3 / VTU v2 there is no global Vue
constructor; register the directive on `config.global.directives`
so it is applied to every test mount.

This unblocks ~112 test files that were failing at setup time with
'Vue is not defined'.

- historyStore: replace Vue 2 set()/del() with direct property
  assignment / delete operator. del() was undefined and threw at
  runtime in tests.
- Test files: replace wrapper.destroy() with wrapper.unmount() for
  Vue Test Utils v2.
- Test files: add explicit describe/it/expect imports where missing
  (vitest globals are disabled).

Addresses ~30 of the remaining test failures (delete operator, VTU v2
unmount API, missing vitest globals). Heading slot rendering and
BootstrapVue compat-mode issues still account for the bulk of the
remaining failures.

happy-dom does not provide Worker, which breaks tests that import
composables using web workers (filter, selectMany). Add a MockWorker
to the global vitest setup mirroring the existing BroadcastChannel
mock.

The two test mock helpers (filter.ts, selectMany.ts) called
`vi.mock` without importing `vi`. With `globals: false` in
vitest.config.mts that throws ReferenceError. Import `vi`
explicitly.
