🎨 Improved Collection Detail UI Hierarchy

Enhanced visual hierarchy and button styling:

✅ Repositioned TCG Tags:
- Moved from header to under description
- Shows only games with cards (dynamic filtering)
- Clean rounded blue tags for better UX

🎯 Improved Button Hierarchy:
- Changed Generate AI Image to ghost outline button
- Changed Invite Collaborator to ghost outline button
- Changed view toggle to white buttons with shadow
- Add Cards remains the only primary purple button

🎨 Visual Improvements:
- Cleaner header with just back button
- Better information flow: title → description → tags → stats
- Consistent ghost styling for secondary actions
- Primary action (Add Cards) now stands out clearly

📱 Enhanced UX:
- TCG tags dynamically show only relevant games
- Clear visual hierarchy guides user attention
- Consistent button styling throughout interface
- Better spacing and information organization

Result: Cleaner, more focused collection interface! 🚀
