Productivity features, UI translations, local email translation

- Snooze (with a Snoozed folder), keyboard shortcuts with a Settings section, mail templates (Compose > More > Templates), a Subscriptions folder with bulk unsubscribe/delete, and tracker blocking with a Privacy toggle (on by default) - Own dialogs instead of browser popups; emoji picker in compose; compose windows survive a visit to Settings - Sentence completion learned from the user's sent mail (no AI) - Interface in English and Polish (one file per language, English as the fallback), picked from the browser on first run, then kept - Email translation on the server via LibreTranslate: Translate button and "Translate to...", messages in several languages translated part by part, names/addresses/emoji/file names/phone numbers kept, an animated line while translating - Antispam "Mark as spam" loads with the message, not when the menu opens Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
