* docs(email): clarify 888888 is opt-in via MULTICA_DEV_VERIFICATION_CODE; document SMTP option in self-host docs
The startup log line, .env.example, and SELF_HOSTING_ADVANCED.md still
implied that the dev master code 888888 is auto-active whenever
APP_ENV != "production". That has not been true since the master code
was gated behind MULTICA_DEV_VERIFICATION_CODE — the fixed code is
disabled by default and must be opted in explicitly.
Also extend the docs site with the SMTP relay backend added in #1877:
auth-setup, environment-variables, and self-host-quickstart now cover
both Resend and SMTP options in EN and ZH.

* docs(email): treat SMTP as an email backend in self-host docs and startup warning
Address review feedback on #2666:
- server: startup warning now fires only when both RESEND_API_KEY and SMTP_HOST
are empty, since either one is a valid email backend. Otherwise the log
mis-tells SMTP-only operators that verification codes go to stdout.
- self-host-quickstart (EN/ZH): tell readers to fetch the verification code
from whichever backend they configured (Resend or SMTP); fall back to
stdout only when neither is configured.
- auth-setup (EN/ZH): \"without Resend\" → \"without any email backend
configured\" so the wording stays correct now that SMTP is a first-class
option.
