Swap the net/smtp mailer for go-mail behind the existing Mailer seam: the Message struct now carries a text + HTML body, TLS mode is chosen from the port (implicit TLS on 465, else mandatory STARTTLS), a dial timeout bounds the synchronous send, and no client certificate is needed. Add a branded, image-free, mobile-friendly ru/en HTML template (with a plain-text alternative) rendering a large readable code and an ignore-notice footer with a landing link. Add BACKEND_PUBLIC_BASE_URL config (the canonical origin for the email footer link, never the request Host — anti-injection), required when a relay is configured. Fix the email-login address squat: ProvisionEmail creates the account flagged is_guest until the code is confirmed, so an abandoned login is reaped like any guest and its address freed; confirming (login or link) clears the flag. Seed the new account's language from the client, plumbed through the email-login request. The confirm deeplink, its transport surface and the send rate-limit land in follow-up work.
