chore(i18n): update i18n translations for modules

* Add and refine Spanish and Italian translations for several modules
  (email, GnuPG info, key-server sync, version checking), replacing
  unfinished placeholders with localized strings.
* Expand and improve Spanish/Italian error message translations for EML
  parsing and email operations to provide clearer guidance and suggested
  remediation steps.
* Update UI labels, warnings and file/size messages to localized text,
  improving UX for Spanish and Italian users.
* Add a new Italian translation TS for the GnuPG info component and
  normalize existing GnuPG translations.
* Remove remaining `type="unfinished"` markers to mark translations as
  completed.

These changes improve localization coverage and clarity without
affecting application logic or behavior.
