New item layouts and dark mode polish
- Two new item layouts for your dishes: Centered elegant, a centered stack for upscale menus, and Casual inline price, which tucks the price right after the name
- Dark mode audit: fixed washed-out and hard-to-read colors across the wizard, billing, invitations, and print orders
- The photo upload area now matches the rest of the app in both light and dark mode
- Plan and billing details now load from one place, so banners, settings, and usage panels always agree
