Major improvements to tenant management:
1. Dynamic field display - Product lists now automatically show all custom fields based on tenant configuration (e.g., inventory, custom attributes)
2. Fixed Jinja2 template scoping issue - Product field values now correctly display in edit forms using selectattr filter
3. Simplified URL structure - Removed redundant /tenant/admin/ routes, all product management now at /tenant/ root
4. Enhanced tenant landing page - Added delete functionality with confirmation modal, shows all custom fields except images
5. Updated all routes and redirects to use simplified paths (/tenant/add, /tenant/edit, etc.)
This consolidates the interface so /tenant/ serves as the main dashboard with full product management capabilities, while /tenant/settings handles configuration.
