What type of PR is this?
Fix: Improve error reporting for unimplemented Query in loaders
What this PR does / why we need it:
This PR refactors the Query methods in pkg/testing/loader_file.go and pkg/testing/loader_non.go.
Previously, these methods did not clearly indicate their inability to perform database queries in a way that aligns with Go's error handling conventions:
fileLoader.Query returned a nil error while passing a "not support" message through the data payload.
nonLoader.Query returned a nil error and an empty result, failing silently.
These behaviors made it harder for calling code to reliably determine if a query was unsupported and could lead to confusion during debugging.
This change modifies both methods to return an explicit, non-nil error (e.g., errors.New("Query functionality is not yet implemented for fileLoader")). This provides:
