Subject: [PATCH] Add MediatR query/handler for reading envelope types

Introduced ReadEnvelopeTypesQuery and its handler to fetch all
envelope types from the repository, map them to DTOs, and
return the result via MediatR. This enables clean, decoupled
retrieval of envelope types in the application.
