Fix Laravel 5.5 compatibility issues - view helpers, collections, and auth routes

- Replace {{ url() }} with {{ url('/') }} in all blade templates to fix object-to-string conversion errors
- Update TeamStoreModel::selectTeamStoreGroupByCartKey() to use first() instead of get() for Laravel 5.5 Collections
- Fix TeamStoreController to access object properties directly instead of using array syntax [0]
- Update authentication routes to use Laravel 5.5 method names (showLoginForm, login, logout)
- Update login/register links from /auth/login to /login throughout views (navbar, app, auth pages)
- Verify cart, login, and register pages working with HTTP 200 status

+### Manual Test
+```bash
+# Build and start container
+docker compose -f docker-compose.local.yml up -d --build
+
+# Check Laravel version
+docker compose -f docker-compose.local.yml exec app php artisan --version
+
+# List all routes (verify new structure)
+docker compose -f docker-compose.local.yml exec app php artisan route:list

+2. **API Prefix**: API routes now automatically prefixed with `/api`

+4. **Middleware**: Web middleware auto-applied to routes/web.php
