Move 39 monitoring, events, and system endpoint test files from NATS.Server.Tests into a dedicated NATS.Server.Monitoring.Tests project. Update namespaces, replace private GetFreePort/ReadUntilAsync with TestUtilities shared helpers, add InternalsVisibleTo, and register in the solution file. All 439 tests pass.
