Which Issue(s) This PR Fixes

• Fixes [Feature] Add independent BrokerConfig switches for Fast Remoting and HA service #11510

Brief Description

Standalone deployments currently cannot disable the Fast Remoting server or the HA service independently. Add two startup options to BrokerConfig, both defaulting to true to preserve existing behavior:

• enableFastRemotingServer=false: do not create the Fast server (listenPort - 2), and skip its processor registrations. Covers ordinary brokers and per-broker sub-servers in BrokerContainer.
• enableHAService=false: do not create or initialize an HA service. This stops the entire service: the HA listener, outbound replication client, GroupTransferService and HAConnectionStateNotificationService are not started. The store lifecycle safely handles an absent HA service.

Disabling HA requires ASYNC_MASTER without controller or slave-acting-master mode. Incompatible configurations fail at the beginning of the store constructor before storage resources are initialized, instead of running replication-dependent modes without an HA service. Existing duplication and DLedger semantics are unchanged; this option does not disable alternative replication implementations.

Both options require a broker restart. Clients must use the main endpoint when Fast Remoting is disabled. BrokerContainer's own management listeners are unchanged. No reflection or changes to replication-mode flags are used.

How Did You Test This Change?

• Linux JDK 8 reactor package, Checkstyle and SpotBugs passed.
• Existing regression tests passed: BrokerControllerTest#testBrokerRestart, testCustomRemotingServer, testBrokerMetricsManagerInitialization; HATest#testHandleHA, testSemiSyncReplica (5 tests, no failures/errors).
• External real-socket harness: all four flag combinations for ordinary Broker and BrokerContainer (8 scenarios), including 100 native Remoting sends/pulls per scenario, Fast sends when enabled, listener/service/thread state, and shutdown. HA-disabled scenarios additionally check absent HA threads, HA status/address-update handling, and persisted-message recovery after restart.
• External HA harness: 100 synchronously acknowledged messages replicated with HA enabled, enabled AutoSwitch compatibility, rejection of incompatible HA-disabled modes, and successful startup with the disabled HA port already occupied.

The external verification harnesses are not included in this PR.

CI follow-up

The first Bazel run built successfully and passed 608 of 609 test targets. TlsTest#disabledServerRejectsSSLClient failed because the TLS-disabled server closed the channel before the client checked its active state, producing RemotingConnectException rather than RemotingSendRequestException. The test and production Remoting implementation were identical to the base branch.

Update that existing test to accept both rejection timings; a successful request still fails the assertion. No production behavior changes are included in this follow-up. The complete 13-test TLS suite passes on Linux JDK 8, along with Checkstyle and SpotBugs. The affected rejection test also passes 30 consecutive runs on Linux JDK 8. A fresh PR CI run has been triggered and is waiting for a runner.
