Standalone AI image generation in email and form editors

Users can now create visuals on the spot when adding or replacing images in Reach's email and form editors. The feature includes an image gallery combining Generated, Uploads, and Free images in one place. Image generation accepts a prompt plus optional style choices (Realistic, Illustration, Flat design, 3D render, Minimalist), layout options (Banner, Horizontal, Vertical, Square), and an optional reference image. Each generation produces 4 variations to preview and choose from, with generated images automatically saved to the library for later download or reuse.
