Fix Postmark mail transport by using core mailer_dsn config

Browse source 
Drupal core's symfony_mailer plugin reads system.mail.mailer_dsn directly
from settings.php — the mailer_transport module entity system is only a UI
layer and is not consulted when actually sending mail. Removed the
mailer_transport entity setup from the entrypoint and configured the DSN
correctly via $config overrides in settings.php instead.
