## Summary

`apps/desktop-ui/`
- Delete both shim files (`src/utils/tailwindUtil.ts` and
`apps/desktop-ui/src/utils/tailwindUtil.ts`)
- Add explicit `@comfyorg/tailwind-utils` dependency to
`apps/desktop-ui/package.json`

`docs/guidance/design-standards.md`, and
`docs/guidance/vue-components.md`

## Summary
Migrate 13 component test files from @vue/test-utils to
@testing-library/vue as Phase 1 of incremental VTL adoption.
## Changes
- **What**: Rewrite 13 test files (88 tests) to use `render`/`screen`
queries, `userEvent` interactions, and `jest-dom` assertions. Add
`data-testid` attributes to 6 components for lint-clean icon/element
queries. Delete unused `src/utils/test-utils.ts`.
- **Dependencies**: `@testing-library/vue`,
`@testing-library/user-event`, `@testing-library/jest-dom` (installed in
Phase 0)
## Review Focus
- `data-testid` additions to component templates are minimal and
non-behavioral
- PrimeVue passthrough (`pt`) usage in UserAvatar.vue for icon testid
- 2 targeted `eslint-disable` in FormRadioGroup.test.ts where PrimeVue
places `aria-describedby` on wrapper div, not input
