fix: Updates dependencies and adds user deletion

Updates System.Text.Json package to version 8.0.5.
Adds functionality to delete users via the API.
Removes the redundant dependency injection extension project and merges it into the main SDK project.
This simplifies the project structure and avoids circular dependencies.
