Fix hardcoded user-facing strings — localize email fallbacks, API errors, AI parse messages
- Frontend: update extractApiError to check body.code first via i18n 'error.<code>' keys;
add en/ro translations for cv_file_missing, captcha_verification_failed, request_cancelled
- email-data migration: seed 6 fallback template keys (match N/A, subject label, unknown IP,
job search results empty states for keywords/providers/location)
- EmailApiEmailSender: replace "N/A", "Job", "Unknown" literals with template lookups
- CvSearchEmailSender: replace "none detected", "none", "-" literals with template lookups
- cv-matcher-data migration: seed parse-error.summary and parse-error.recommendation in AiPrompts
- CvMatcherService: look up localized parse-error messages from AiPrompts before calling ParseResult
Closes #53
