Add filtering for non-null OutRes in ReadRecActionQuery

Enhanced the `Handle` method in `ReadRecActionQueryHandler`
to include an additional filtering condition when querying
the repository. The query now filters actions where
`RootAction.OutRes` is not null, in addition to matching
the `ProfileId`. This ensures that only relevant actions
with a valid `OutRes` are included in the result set.
