Updated the MJML integration to [email protected] for newer email builder compatibility.
Expanded the email editor's mj-section styling support with text-align, border-radius, and gap controls.

Polished the embedded editor shell with built-in color picker styling, a style-properties toolbar shortcut, and more usable import/export code panels.
