[I] extend HuggingFaceImageUploadComponent template coverage [texera]

   ### Task Summary
   
   `HuggingFaceImageUploadComponent`'s **template** is at ~39% (`hugging-face-image-upload.component.html`, 11 uncovered lines of 51) while its class file is already at **100%** — the handlers are unit-tested, but the preview panel never renders, so its bindings stay uncovered. Bring the template to full coverage. Vitest/jsdom; see `frontend/TESTING.md`.
   
   ### Behavior to add
   
   Extend `hugging-face-image-upload.component.spec.ts` so the preview branch renders, then run the coverage report and cover the remaining red lines. The gap is the selected-image panel: the `<img [src]="previewSrc">`, the `hf-image-meta` block with `{{ displayFileName || "Selected image" }}`, and the `(click)="clearImage(fileInput)"` button.
   
   Approach:
   - Put the component in the "image selected" state (set `previewSrc` / `displayFileName` through the same path the component uses) and `fixture.detectChanges()` so the preview panel renders.
   - Assert the `img`'s bound `src` and the displayed name, plus the fallback text when `displayFileName` is empty ("Selected image").
   - Click the clear button via `fixture.debugElement.query(By.css("..."))` + `.triggerEventHandler("click", ...)` and assert `clearImage` reset the preview state (the panel disappears after a further `detectChanges()`).
   
   Assert on rendered attributes/text — not on layout or geometry (zeros under jsdom).
