Will Miao e914a0e19d fix(ui): reconcile model listing in place after download (#1078)
Stop resetting the whole listing after a successful download. The legacy
flow reloaded page 1, scrolled to the top and hijacked the sidebar's
active folder whenever a custom target folder was used, which made the
Updates view lose its place (and sometimes render as an empty page).

Downloads only flip the update flag for one model, so the listing is now
reconciled in place through the virtual scroller:

- Updates view: the model's cards are removed once its newest eligible
  version is installed (the flag is model-level).
- Normal listing: the card stays; only update_available is cleared.
- Model not in the current view (different folder/filter/window):
  no-op; the sidebar folder tree alone is refreshed.
- Falling back to the legacy reload only when no virtual scroller is
  available (e.g. recipes page, duplicates mode, HF downloads).

* - Normal listing: the card stays; only the update flag is cleared.
* - The model is not in the current view (different folder / filter /
* window): nothing changes, which also covers brand-new models whose
* card did not exist before.
*
* The sidebar folder tree is refreshed separately so folder counts
* stay accurate without touching the model listing or scroll position.
