* Studio: fix Downloaded model list disappearing and order it by last download
The chat model picker scan for cached GGUF and safetensors models aborted
whenever an auxiliary Hugging Face cache dir (such as ~/.cache/huggingface/hub)
was unreadable, returning an empty list. That hid the Downloaded section and
let already downloaded models appear under Recommended. Isolate each cache
probe so an inaccessible directory is skipped instead of failing the scan.
Also order Downloaded newest-first using cached blob mtimes (multi-quant repos
group by their most recent quant), keep the section visible while searching,
and make the per-quant downloaded check per-snapshot and mmproj aware so a
Recommended quant is never falsely marked downloaded.

* Studio: harden gguf-variants scan and dedupe by newest timestamp
Guard f.stat() per file so a broken symlink or unreadable file in a
snapshot no longer aborts the downloaded check early, and match quant
labels case-insensitively. When the same repo is present in multiple
caches with equal size, keep the newest last_modified so Downloaded
ordering reflects the most recent copy.

* Studio: apply cache-scan guards to sibling endpoints found in review
Extend the inaccessible-cache guard and mmproj/stat hardening to the
parallel HF cache code paths flagged in review:
- list_local_models and the Hub inventory scan now skip an unreadable
auxiliary cache instead of returning 500.
- The GGUF download-progress endpoint excludes mmproj adapters and
guards f.stat() so one bad file does not zero a repo's progress.
- The offline snapshot scanner guards its is_dir() probes.
- The chat-only picker no longer renders a blank list when a search
matches only cached non-GGUF models.
