Remove query execution tracking properties

Simplified the codebase by removing `BodyQueryExecuted`,
`HeaderQueryExecuted`, and related computed properties
(`IsBodyQueryReturnedNoData` and `IsHeaderQueryReturnedNoData`)
from `RecActionDto`. These properties were used to track
whether `BodyQuery` and `HeaderQuery` were executed and
whether they returned data.

Updated `BodyQueryBehavior` and `HeaderQueryBehavior` to
remove logic that set these properties. Also removed the
conditional block in `InvokeRecActionCommandHandler` that
logged warnings based on these properties.

These changes streamline the code and reflect a shift away
from tracking query execution and results at this level.
