Add translations for French, German, Portuguese, Italian, Basque and Greek. (#77)

* fix(i18n): align English copy with Catalan source and sync JSX defaults

  - Realign locales/en/common.json against locales/ca/common.json (source of truth).
    Notable changes: about_us brand statement and tabs values, FAQ free/setup/gdpr
    answers, hero subtitle/trusted_by, target_users description/list, comparison
    and footer sentence-case, Òmnium diacritic, swapped New Belarus value/label,
    "impugnments" -> "disputes", "catalan" -> "Catalan".
  - Unify the primary CTA to "Start for free" across hero, app_landing,
    use_cases_page, and FAQ.
  - Sync stale JSX t() defaults with the updated JSON across components/,
    lib/page-meta.ts, and pages/*/+title.ts so fallbacks no longer drift.

* fix(i18n): polish Spanish locale and align with EN source

  - Replace wrong items.8 testimonial in es (was a fictitious "Federación
    Deportiva"; now the proper BLOOCK quote matching en/ca).
  - Fix mistranslations: "Confianza Probable" -> "Confianza Demostrable",
    "entidad civil" -> "entidad cívica", "Cumple con GDPR" / "GDPR compliant"
    -> "Cumple con el RGPD".
  - Sync about_us mission/values, faq answers, and target_users copy with
    the polished EN source.
  - Unify primary CTA to imperative "Empieza gratis" and secondary to
    "Habla con un experto" across hero, app_landing, use_cases_page, FAQ.
  - Sentence-case and proper-noun fixes (Òmnium Cultural, Bisbalenc/a de
    l'Any, "Directora ejecutiva", "¡Seguiremos"); replace double-spaced
    em-dash leftovers with " - "; "Compañía" -> "Empresa".

* feat(i18n): write fresh German translation aligned with source

  - Replace stale, key-mismatched de/common.json with a full translation
    mirroring en's current key structure (0 missing, 0 extra keys).
  - Use formal "Sie" address (German B2B convention), DSGVO instead of
    GDPR, German number formatting (200.000, 77,12 %, 50 €), and
    naturalized idioms ("gleiche Ausgangsbedingungen", "manipulationssicher",
    "Allgemeine Geschäftsbedingungen").

* feat(i18n): write fresh Greek translation aligned with EN source

  - Replace stale, key-mismatched el/common.json with a full translation
    mirroring en's current key structure (0 missing, 0 extra keys).
  - Use formal "εσείς" address (B2B convention), Greek acronyms
    (ΓΚΠΔ, ΟΟΣΑ, ΕΕ), Greek number formatting (200.000, 77,12%, 50 €),
    and naturalized terms ("ανοιχτός κώδικας", "απαραβίαστος",
    "Όροι και προϋποθέσεις").

* feat(i18n): write fresh Italian translation aligned with EN source

  - Replace stale, key-mismatched it/common.json with a full translation
    mirroring en's current key structure (0 missing, 0 extra keys).
  - Use informal "tu" address (modern Italian SaaS convention), keep
    GDPR as the standard term, render numbers Italian-style (200.000,
    77,12%, 50 €), and naturalize phrasing ("inalterabile", "ente
    civico", "Ordine Professionale degli Infermieri").

* feat(i18n): write fresh Portuguese translation aligned with EN source

  - Replace stale, key-mismatched pt/common.json with a full translation
    mirroring en's current key structure (0 missing, 0 extra keys).
  - Use European Portuguese (pt-PT) given the European brand context:
    "registo", "câmara municipal", "folha de cálculo", "contacto",
    "separador", and pt-PT progressive forms ("a enviar").
  - Use formal address (3rd-person imperatives, "a sua"), Portuguese
    acronyms (RGPD, OCDE, UE), Portuguese number formatting (200.000,
    77,12%, 50 €), and naturalized terms ("código aberto", "inviolável",
    "Presidente da Câmara").

* feat(i18n): add support for French and Basque (Euskera)

  - Register 'fr' and 'eu' in locales/index.ts (Locale type, locales
    array, availableLocales) - both commented out in the active list
    pending review.
  - Add locales/fr/common.json: full professional French translation
    with formal "vous" address, French typography (« » guillemets,
    narrow spaces, RGPD, OCDE, "200 000", "77,12 %"), and naturalized
    idioms ("égaliser les chances", "Conditions générales").
  - Add locales/eu/common.json: full Basque (Euskera) translation with
    formal "zu" address, Basque acronyms (RGPD, ELGA), and pre-number
    percent style (%30). Native Basque review recommended before
    activation.

* feat(i18n): activate de, el, fr, it, pt locales

  - Add German, Greek, French, Italian, and Portuguese to the active
    locales array and uncomment them in availableLocales.
