Review flow and email metadata

This week improves the path from editing to review, with better approval controls, richer email metadata, and more useful Betty context.

+Improvements

• Campaign EditorSubject lines and preheaders can now be edited directly in Better Email, so campaign metadata can stay with the email while it moves through review and export.
• Review & approvalsReview comments, approvals, and handoffs now have clearer controls, making the path from draft to approval easier to follow.
• Betty AIBetty can now work with document attachments and rendered screenshots, making it easier to explain what you need without rewriting context by hand.
• Design SystemsRich text template inputs can now include a custom tag toolbar, so teams can insert approved dynamic fields from the editor.
• Campaign EditorAPI users can now work with recipient fields used for personalization and segmentation. The docs now include setup, authentication, error handling, and endpoint references for recipient fields.
• Workspace & adminUsers can now manage their Better Email profile settings from inside the app.

• Campaign EditorSegment names are now checked in the right scope, reducing false conflicts when similar names are valid in different contexts.
• Campaign EditorDesign SystemsNew emails now follow the latest published template revision instead of staying pinned to an older version.
