feat: bring back the newsletter subscription plugin

The "Newsletter-/RA-Registrierung" plugin (epproducts_newsletter_subscription)
subscribes to the Mailjet lists through the MyE&P API and is still in use on
the newsletter, travel alert and travel for groups pages; retiring it in
49b96df was a mistake. Controller and templates come back from a46918d,
ported to TYPO3 13 (actions return responses). The DTO and the API client
calls were still in place. The "newsletter" result message plugin (index
action) is not part of this.
