🎯 RESTORE: Enhanced admin user management functionality

✅ Added user search functionality to admin users page
✅ Created comprehensive user detail template with:
   - Complete user information display
   - User action buttons (activate/deactivate/delete)
   - Quotation history for each user
   - Improved tooltips and responsive design
✅ Enhanced admin users table with better action buttons
