feat(i18n): backfill Catalan (ca) translations (AI-generated, needs review)

[rusackas]

SUMMARY

Backfills the remaining untranslated entries in the Catalan (ca) catalog using scripts/translations/backfill_po.py (Claude, cross-language context), skipping do-not-translate tokens (icon names, enum values, SQL keywords, API field names, placeholders — see #41651).

All generated strings are marked #, fuzzy with an attribution comment. The #, fuzzy flag marks each entry as machine-generated and needing native-speaker review. Note on serving: both the frontend (po2json --fuzzy) and backend (pybabel compile --use-fuzzy, see #41648) builds include fuzzy entries, so these translations render in the UI once built — reviewers should verify each and remove the #, fuzzy flag to confirm. Format placeholders are preserved (verified programmatically).

Tracked by check_translation_regression.py as untranslated → fuzzy, which is explicitly not a regression. Part of a per-language sweep.

BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF

Translation catalog only — no layout or behavior change. Strings render once the frontend/backend are rebuilt.

TESTING INSTRUCTIONS

• pybabel compile --use-fuzzy -d superset/translations -l ca succeeds.
• Catalan native speakers: review the #, fuzzy entries and de-fuzz once confirmed.

ADDITIONAL INFORMATION

• Has associated issue:
• Required feature flags:
• Changes UI

  • Incorrect translation for API key · Line 1038-1039
    The msgstr 'El nom del rol és obligatori' (Role name is required) is incorrectly used for 'API key name is required'. This appears to be a pre-existing copy-paste error from the 'Role name is required' entry at line 11780. Catalan users will see 'El nom del rol és obligatori' when the English text says 'API key name is required', causing confusion.
  • Translation fuzzy flag review needed · Line 847-851
    All newly added Catalan translations are marked with #, fuzzy flag indicating machine-translation without human review. While the translations appear semantically accurate (e.g., 'API key revoked successfully' → 'La clau API s'ha revocat correctament'), the fuzzy flag should be removed after a Catalan-speaking reviewer verifies each entry.
  • Fuzzy entries need human review before use · Line 9082-9096
    The backfill script intentionally marks AI-generated entries as `#, fuzzy` so they are excluded from runtime translation until reviewed (per `howtos.md` lines 403-408). All 5 new fuzzy entries added in this diff need human review before the flag is removed — particularly the longer multi-line strings where placeholder alignment and context preservation are harder to verify.

The flagged issue is correct. The Catalan translation "Aquest és un missatge d'error personalitzat per a a" contains a duplicated "a" at the end, which is grammatically incorrect and unprofessional. To resolve this, you should quote the identifier or rephrase the sentence to avoid the repetition. For example, you could change the translation to: msgstr "Aquest és un missatge d'error personalitzat per a \"a\"".

I have checked the PR comments, and there are no other comments to address. Would you like me to implement this fix for you?

msgid "This is custom error message for a"
-msgstr "Aquest és un missatge d'error personalitzat per a a"
+msgstr "Aquest és un missatge d'error personalitzat per a \"a\""
