Refactored `ReadOutResQuery` to a record type implementing
`IRequest<OutResDto>` for MediatR. Introduced `ReadOutResHandler`
to handle the query, leveraging `IRepository` and `IMapper` for
database access and mapping. Added support for filtering by
`ActionId` and asynchronous query execution. Streamlined design
by moving `ProfileId` and `ActionId` to immutable `init`
properties in the record.
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.
Added a new `OutResDto` record in the `ReC.Application.Common.Dto` namespace to represent output result data with properties like `Id`, `ActionId`, `Header`, `Body`, and audit fields.
Added a new `ReadOutResQuery` class in the `ReC.Application.OutResults.Queries` namespace to facilitate querying output results based on `ProfileId` and `ActionId`.
