fix: don't require email infra on self-hosted, improve login form detection

- sendTransactionalEmail no-ops (with a warning) when no mail transport is
  configured instead of throwing — sign-up 500'd on SMTP-less instances
- sendVerificationEmail catches transport failures so a broken SMTP can't
  block account creation; verification stays optional (requireEmailVerification
  was never set)
- login form gains id/name attributes and label for/id pairing so password
  managers (Proton Pass et al.) detect the fields; email input uses
  autocomplete=username
