Feature: #88470 - Custom message in form email finisher 

See forge#88470

Description 

The email finishers (EmailToSender and EmailToReceiver) of the TYPO3 form framework now support an optional custom message field. This allows editors to add a personalized text to the email sent by the form, either before or after the submitted form values.

The message field supports rich text editing using the form-content RTE preset, which provides formatting options like bold, italic, links, and lists.

A special placeholder {formValues} can be used within the message to control where the submitted form data table is rendered. If the placeholder is omitted, only the custom message is shown and the form values table is hidden.

The message field is available in:

  • The form editor backend module
  • The form finisher override settings

Impact 

Editors can now configure a custom message for email finishers directly in the form editor or via finisher overrides in the form plugin. This provides more flexibility in crafting email notifications without the need for custom Fluid templates.
