mrhid6andClaude Opus 5 aef5811c16 fix(admin): SMTP over implicit TLS, and rollbacks that survive ...

Two bugs, one symptom: signup created an account and a customer_user but
no verification email ever arrived.

net/smtp.SendMail only speaks STARTTLS. Against a port-465 server, which
expects a TLS handshake immediately, it never delivers. The transport now
wraps the connection before speaking SMTP on 465, exactly as
sitesvc/internal/mail already did — the two are duplicated, so change both
or consolidate into shared/. Also adds Date and Message-ID, whose absence
gets a message scored as spam, and a 15s deadline on the conversation.

The rollbacks ran on the HTTP request's context. A stalled mail server
holds the request until the browser gives up, which cancels that context
and turns both rollbacks into silent no-ops — stranding the exact rows
they exist to remove. They now run detached with their own timeout, and
log when they fail.
