feat(models): show Civitai model/version ids in model modal, always-on hash/id search

- Model modal hash footnote now shows Civitai model id and version id
  (right-aligned, quick-copy buttons); hidden for non-Civitai models
- Hash/id exact search (sha256/autov2/autov3/civitai ids) is now always
  on: the search-options "hash" toggle is removed and the search_hash
  query param is silently ignored for API compatibility
- Footnote render condition relaxed so autov3-only and id-only models
  still show the line
- i18n: 4 new keys translated in all 9 locales; filters.hash key removed

+### Civitai ids feature (model/version id in the model modal)
+
+The model modal's hash footnote shows the Civitai **model id** and **version id** with
+copy buttons (`modals.model.metadata.civitaiModelId` / `.civitaiVersionId` labels,
+`modals.model.actions.copyCivitaiId` tooltip, `.civitaiIdCopied` toast). **"ID" stays
+Latin in every locale** (same precedent as `recipes.*.copyId`), and `Civitai` is the
+brand (R3) — it is never translated or transliterated; the casing mirrors `en.json`
+verbatim (R9). The copy/copied strings reuse each locale's existing clipboard patterns
+(`modals.model.actions.copyHash` / `openFileLocation.copied`).
