pptx704 11928a172a feat: send email notification on account hard-delete
Notify users via email when their account is permanently deleted after
the 15-day soft-delete grace period. Query now returns email alongside
user ID so the notification can be sent after deletion.

Email failure is logged as a warning but does not block cleanup.
