refactor: extract NATS.Server.Gateways.Tests project

Move 25 gateway-related test files from NATS.Server.Tests into a dedicated NATS.Server.Gateways.Tests project. Update namespaces, replace private ReadUntilAsync with SocketTestHelper from TestUtilities, inline TestServerFactory usage, add InternalsVisibleTo, and register the project in the solution file. All 261 tests pass.
