Changes (by file)

• DashAI/front/src/pages/home/Home.jsx:
  • Footer: replaced hardcoded v0.9.3-alpha - MIT License with © {currentYear} dashAI - MIT License (year auto-updates, no version to keep in sync).
  • Community links: replaced Forum/Discord(#)/Twitter placeholders with Discord (discord.gg/n9y2hEjFng), Mailing List (groups.google.com/g/dashai-updates), and direct email (mailto:dashai.nocode@gmail.com); updated icons and imports accordingly.
  • Link target: _blank now applies only to http links so mailto: no longer opens a blank tab.
• DashAI/front/src/utils/i18n/locales/{en,es,pt,de}/home.json: added mailingList and directMail labels, removed forum and twitter.

---

Testing

• Open the Home page and confirm the three community links open correctly (Discord/Google Group in a new tab, email opens the mail client with no blank tab).
• Switch language (en/es/pt/de) and verify the new link labels render translated.

---

Notes

• The footer no longer displays an app version; if a version is wanted later, it should be sourced dynamically (backend endpoint or build time injection) rather than hardcoded.
