• Fixes [Feature] Add enableGrpcChannelReceiptHandleRenew switch to disable proxy receipt handle periodic renewal for gRPC clients #10278

Brief Description

This PR adds a new dynamic switch enableGrpcChannelReceiptHandleRenew in ProxyConfig to allow disabling the proxy's periodic receipt handle renewal mechanism specifically for gRPC (GrpcClientChannel) consumers.

Background: The current auto-renew approach uses a short invisible time (~60s) and periodically calls changeInvisibleTime to extend it. While this protects against client crashes, it has a critical flaw: if the proxy crashes, the client's original handle (issued with short invisible time) has already expired, and the renewed handle is lost in proxy memory. The client cannot ack through another proxy, causing unavoidable duplicate consumption.

Changes:

1. ProxyConfig.enableGrpcChannelReceiptHandleRenew (default true): New boolean switch targeting only gRPC channels. When set to false:

   • The proxy uses the consumer group's consumeTimeoutMinute (from SubscriptionGroupConfig) as the invisible time during pop for gRPC clients, giving the client a long-lived handle.
   • The proxy skips periodic changeInvisibleTime renewal calls for GrpcClientChannel instances only.
   • Non-gRPC channels (e.g., Remoting) continue to renew normally.
   • Handle storage and client-disconnect cleanup (nack) are preserved.

2. ReceiveMessageActivity: When enableGrpcChannelReceiptHandleRenew=false, resolves the invisible time from the group's consumeTimeoutMinute instead of the short defaultInvisibleTimeMills.

3. DefaultReceiptHandleManager: When enableGrpcChannelReceiptHandleRenew=false, the scheduled task still detects client disconnects (and nacks), but skips the periodic renewal loop only for channels that are instanceof GrpcClientChannel.

How Did You Test This Change?

1. Verified compilation passes (mvn compile -pl proxy -am).
2. Verified no IDE errors in all modified files.
3. Existing unit tests in DefaultReceiptHandleManagerTest and ReceiptHandleProcessorTest continue to pass (they test with default enableGrpcChannelReceiptHandleRenew=true).
