Refactor query behaviors for execution tracking

Refactored `BodyQueryBehavior` and `HeaderQueryBehavior` to introduce explicit execution tracking with new properties (`BodyQueryExecuted` and `HeaderQueryExecuted`). Updated `RecActionDto` to include computed properties (`IsBodyQueryReturnedNoData` and `IsHeaderQueryReturnedNoData`) for clearer null-checking logic. Removed the `IsReturnedNoData` tuple for simplicity.

Updated `InvokeRecActionCommandHandler` to use the new `IsBodyQueryReturnedNoData` property. Improved logging for better diagnostics and clarified handling of null results in query behaviors.
