Deprecate methods and streamline controller code

Added [Obsolete("Use MediatR")] attribute to several methods
across `DocumentController`, `HomeController`,
`TestConfigController`, `TestDocumentReceiverElementController`,
and `TestEnvelopeController` to indicate they should no longer
be used.

Refactored constructors in `TestConfigController` and
`TestEnvelopeController` to remove unnecessary empty blocks.

Improved formatting and structure of the `GetAll` method in
`TestEnvelopeController` for better clarity while maintaining
functionality.

Updated `Program.cs` to suppress warnings about obsolete
types/members during service registrations, indicating a
transition to newer implementations.
