i18n: refresh the download copy for ModelScope in 9 locales

The download dialog's URL field still said "CivitAI URL(s)" and rejected
anything that was not CivitAI, and the hint listed only CivitAI / CivArchive /
Hugging Face. Four en.json values were refreshed in the previous commit and
propagated here:

- modals.download.civitaiUrl -> "Model URL(s)" (模型 URL / モデル URL / modèle /
  Modell / modelo / модель / מודל).
- modals.download.urlHint names all four supported sites.
- modals.download.errors.invalidUrl -> "Invalid model URL format"; it is the
  generic "unrecognised URL" error, so naming CivitAI was wrong.
- modals.download.errors.mixedSources names Hugging Face / ModelScope.

Brand names stay Latin per R3, "model" follows the §2/§5 rendering already in
force in each locale, and the Latin/Cyrillic/Hebrew files keep ASCII
punctuation. en.json is unchanged in this commit; exactly four lines change in
each of the nine locale files, with no reindentation — the sync script does not
refresh an existing key's value, so this was done by exact-literal replacement.

pytest tests/i18n: 20 passed and sync_translation_keys.py --dry-run is a no-op.
