Fix public header mobile menu and content formatting

Public Header Mobile Menu:
- Added hamburger menu for non-logged-in visitors on mobile
- Desktop shows full navigation, mobile shows slide-out menu with icons
- Cart icon remains visible on mobile alongside hamburger

Tiptap Editor List Formatting:
- Added visual styling for bullet lists (disc markers, padding, spacing)
- Added visual styling for ordered lists (decimal markers, padding, spacing)
- List markers now use primary color for better visibility

Product Content HTML Formatting:
- Enhanced prose styling with proper heading sizes (h1, h2, h3)
- Improved list formatting with proper indentation and markers
- Added blockquote styling with left border and italic text
- Added code and preformatted text styling
- Ensures all formatted content displays properly on product detail pages
