fix: Improve error message in mongoFieldToParseSchemaField with field and class details

- Add fieldName and className parameters to mongoFieldToParseSchemaField function
- Update error message to include specific field name and class information
- Show collection name (_SCHEMA) and document ID for better debugging
- Pass field name and class ID from mongoSchemaFieldsToParseSchemaFields
- Enhanced error message format: 'Invalid field type: X for field Y in class _SCHEMA (id: Z)'
- Improves developer experience by providing clear context for schema validation errors
