Move 225 JetStream-related test files from NATS.Server.Tests into a dedicated NATS.Server.JetStream.Tests project. This includes root-level JetStream*.cs files, storage test files (FileStore, MemStore, StreamStoreContract), and the full JetStream/ subfolder tree (Api, Cluster, Consumers, MirrorSource, Snapshots, Storage, Streams). Updated all namespaces, added InternalsVisibleTo, registered in the solution file, and added the JETSTREAM_INTEGRATION_MATRIX define.
