Make ProfileId and ActionId properties nullable

Changed the `ProfileId` and `ActionId` properties in the
`ReadOutResQuery` class from non-nullable `long` to nullable
`long?`. This allows these properties to hold `null` values,
making them optional for scenarios where they are not always
required or applicable.
