fix: resolve validation false positives for Google Drive fileFolder resource
- Add normalizeNodeType to enhanced-config-validator to fix node type lookups - Implement getNodePropertyDefaults and getDefaultOperationForResource in repository - Apply default values before checking property visibility - Remove incorrect node type validation forcing n8n-nodes-base prefix - Add comprehensive tests for validation fixes Fixes validation errors for perfectly working workflows like EOitR1NWt2hIcpgd
