feat(server): Option to configure SMTPS transport (#22833)

* feat(server): Option to configure SMTPS transport

This commit adds a boolean option in the SMTP transport configuration to
enable the so-called "secure" mode. What it does is use SMTP over TLS
instead of relying on the more common STARTTLS option over plain SMTP.

* Add missing field in dto

* Add missing field

* Use a switch instead of text field

* Add field in spec

* chore: regen open-api
