fix(i18n): add common.close to en + de locales

The device-sync migration modal uses t('common.close') for its dismiss
button, but the key lived only inside scoped namespaces (where it had
different translations like "Verstanden" / "Got it"). Add the
straightforward "Schließen" / "Close" under common so the migration
modal shows the right label.

 > **🎉 macOS users:** Starting with **v1.40.0**, Psysonic is signed + notarized and can **update itself silently**. No more DMG downloading and dragging to Applications — the updater fetches the signed `.app` bundle, verifies the signature, replaces the app in place, and relaunches. Just click "Install now" when the update notification appears.

-> **📦 Version jump 1.34.x → 1.40.0:** The 1.34.x patch series was bumped a lot as each small feature landed. 1.40.0 consolidates the last few months of work — macOS signing + auto-updater, the Device-Sync overhaul, theme work and contrast audits — into a single coherent release. The next major bump (2.0.0) is planned once Windows code-signing + Windows auto-updater are active as well.
