Will Miao dc715aa273 fix(download): fallback to downloadUrl when all mirrors are deleted ...

When Civitai returns 404 for /models/{id} (e.g. due to Civitai API bug
where un-deleted models still get 404), the fallback to CivArchive
provides metadata.  However CivArchive may return mirrors with every
entry marked deletedAt, while the file's downloadUrl is still valid.

Before this fix, _build_download_urls_from_file_info used an if/else
that skipped the downloadUrl fallback whenever the mirrors array was
non-empty, even when all mirrors were filtered out.  Now downloadUrl
is always tried when no usable mirror remains.

Also deduplicated the inline mirror-processing code at the second call
site by replacing it with a call to the shared helper.
