Replace the bare-bones inline HTML in notification, verification, and admin test emails with a shared branded layout in internal/mail, matching the web UI's Midnight Cinema theme (dark card shell, wordmark, mono episode-code badges, white primary CTA). The shell is built for email clients: tables + inline styles, explicit dark color-scheme, Outlook-safe button, and a width:100%/max-width pattern so the card shrinks correctly on phones. Plain-text bodies, subjects, and the link-free-when-unconfigured guarantee are unchanged; the admin test email gains an HTML body so the SMTP test doubles as a design preview.
