Add AuthorizedUser entity and DbSet to TaskFlowDbContext

A new `DbSet` property `AuthorizedUsers` was added to the
`TaskFlowDbContext` class to represent keyless results for
authorized users procedure results.

The `OnModelCreating` method was updated to configure the
`AuthorizedUser` entity as keyless, map it to a database view,
and define the `WisagId` property mapping.

Additionally, a new `AuthorizedUser` class was introduced in
the `DigitalData.TaskFlow.Domain.ProcedureResults` namespace
with an immutable `WisagId` property.
