Add integration test project with MediatR procedure tests

Added ReC.Tests project with integration tests for stored procedure commands and queries via MediatR, covering endpoints, actions, results, and profiles. Introduced a test base for DI/configuration, helper for private property access, and updated the solution to include the new test suite. Tests use NUnit and cover both positive and negative scenarios.
