Add QueryRaw and QueryInterpolated methods to repository

Added `QueryRaw` and `QueryInterpolated` methods to the
`IRepository` interface for raw and interpolated SQL queries,
conditionally compiled for the `NET` target framework.

Removed the `Sql` method from `DbRepository` and replaced it
with implementations of `QueryRaw` and `QueryInterpolated`
using `Entities.FromSqlRaw` and `Entities.FromSqlInterpolated`.

Updated the `Query` property in `DbRepository` to use
`Entities.AsNoTracking()` for read-only queries.
