Add Invoked filter to ReadRecActionQuery handler

Introduced a nullable `Invoked` property in `ReadRecActionQueryBase`
to enable conditional filtering of actions based on `Root.OutRes`.
Added a `ToReadQuery` method for easier query conversion.

Refactored `ReadRecActionQueryHandler` to apply dynamic filtering
based on the `Invoked` property:
- `true`: Filters actions with non-null `Root.OutRes`.
- `false`: Filters actions with null `Root.OutRes`.
- `null`: No additional filtering applied.

Replaced hardcoded filtering logic with the new dynamic approach.
