Contextual help & smoother photos

• NewContextual help (ⓘ) across the dashboard — short explanations right where you need them.
• ImprovedListing photos now support drag-and-drop reordering with a smoother upload flow — the same drag-and-drop works for header, featured and category images.
• ImprovedGuidebooks auto-save with an undo option, and you can add your listing's cover photo as the first slider slide.
