fix: resolve custom content page refresh and MCP is_enabled errors

1. Fixed page refresh showing "no custom content" briefly:
   - Added loading state check while shop is being determined from URL
   - Shows loading spinner instead of "no content" during initialization
   - Added "noShopSelected" message when no shop is available

2. Fixed MCP list_custom_contents tool error:
   - Removed non-existent is_enabled column from query
   - Column doesn't exist in custom_content table
   - All content is now treated as enabled

Added translations for noShopSelected in EN, DE, HU.
