feat: improve model scan cache override, combo UX, and filename handling

- Add force_rescan end-to-end so callers can bypass the short-lived local model scan cache: backend entry in __init__.py and core/resolver.py, lifecycle_graph_methods forwards it through the workflow analysis body, and download_target_methods passes ?force=1 from the refresh flow.
- Rewrite combo dropdown lifecycle in missing_browser_methods with show/hide helpers, pointer-capture tracking, and a capture-phase outside-click listener so the list stays open during drag/hover and closes reliably otherwise.
- Animate refresh buttons (CSS keyframes + JS Web Animations) with reduced-motion fallback.
- Encode selected model path into the selected-bar data-model attribute and wire contextmenu so users can open the containing folder from the selection.
- Fix XSS risk in selected-bar label by escaping label HTML; change queue/selected Remove buttons to danger style.
- Increase max missing-browser model column width clamp from 430 to 820 and stop truncating missing-filename display; show full filename with tooltip instead.
- Update huggingface-author-index.json metadata timestamp/counts (1 file changed, 1 line).
