Update package references and modify DbRepository access

- Added conditional package references for AutoMapper in
  `DigitalData.Core.Application.csproj` to support
  different target framework versions.

- Changed `DbRepository` class access modifier from
  `public` to `internal` to encapsulate implementation
  details within the current assembly.
