Fix Groovy syntax error in MCP screen discovery service

- Fixed missing opening brace and alignment issues in fallback logic
- Removed duplicate log statement and extra closing brace
- Screen discovery now works correctly for nested subscreens
- Product.FindProduct tool now properly discovered under Catalog hierarchy

Resolves broken MCP tool hierarchy where subscreens were missing from tools list.
