SmtpEmailService (nodemailer 9.0.5, exact-pinned) behind the existing EmailService seam. Provider resolution: EMAIL_PROVIDER wins, else RESEND_API_KEY selects Resend (hosted byte-identical), else SMTP_HOST selects SMTP. From header is built exactly like the Resend service after #1956 (no 'via <app>', fromAddress honored, platform-sender retry). STARTTLS is required by default (requireTLS) with SMTP_REQUIRE_TLS=false as an explicit opt-out for a plaintext LAN relay. Docs, env examples and the generated extension registry updated.

|
|
* adding SMTP variables on the side can never move hosted mail.
|
|
* 3. SMTP_HOST present: SMTP. The sovereign self-host path.
|
|
* 4. Otherwise Resend, whose isConfigured() is false, so email-dependent
|
|
* features degrade exactly as before (PDF download, no send).
