Remove unused projects and simplify solution structure

The following projects were removed:
- `DigitalData.MessagingService.Client.Infrastructure`
- `DigitalData.MessagingService.Client`
- `DigitalData.MessagingService.Publisher.Abstraction`

The solution file (`DigitalData.MessagingService.sln`) was updated to remove references to these projects, including solution configuration platforms and nested project sections.

Additionally, the `DigitalData.MessagingService.Application.csproj` file was updated to remove a `ProjectReference` to `DigitalData.MessagingService.Publisher.Abstraction.csproj`.

These changes streamline the solution by removing unused or redundant components and reducing dependencies.
