feat(api): add loader_metadata to ADBDataAPI response

[Sodawyx]

This commit enhances the ADBDataAPI by including the loader_metadata field in the response structure for both the async template and data API. This addition allows for better tracking and management of loader-specific metadata associated with matches. Additionally, the example knowledgebase configuration has been updated to reflect a new ADB knowledge base name and modified query execution.
