feat: Wave 6 batch 2 — accounts/auth, gateways, routes, JetStream API, JetStream cluster tests
Add comprehensive Go-parity test coverage across 5 subsystems: - Accounts/Auth: isolation, import/export, auth mechanisms, permissions (82 tests) - Gateways: connection, forwarding, interest mode, config (106 tests) - Routes: connection, subscription, forwarding, config validation (78 tests) - JetStream API: stream/consumer CRUD, pub/sub, features, admin (234 tests) - JetStream Cluster: streams, consumers, failover, meta (108 tests) Total: ~608 new test annotations across 22 files (+13,844 lines) All tests pass individually; suite total: 2,283 passing, 3 skipped
