[FIX] web_editor: disable dropImageAsAttachment for mail and mailing

This commit deactivates the conversion of pasted or dropped images into
attachments through a controller within the web_editor module. This
alteration applies to mail and mass_mailing modules, as they have their
own mechanism to handle this process.
