The Query methods in fileLoader and nonLoader previously either returned a "not support" message via the data payload (fileLoader) or failed silently (nonLoader), both with a nil error. This commit changes them to return explicit non-nil errors, indicating that the Query functionality is not implemented for these loader types. This aligns better with Go's error handling conventions and provides clearer feedback to callers.

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:
