[Backport release-1.19] fix(workflow): accept work items larger than gRPC's 4MB default - #1339

The workflow worker's gRPC channel kept gRPC's default 4MB receive limit unless the app set max_grpc_message_length or DAPR_GRPC_MAX_INBOUND_MESSAGE_SIZE_BYTES. The sidecar sends work items up to its own max body size, which apps raise for large payloads, so a work item over 4MB (for example a fan-out of five 1MB activity results) failed the stream with RESOURCE_EXHAUSTED. The worker reconnected, the sidecar redelivered the same work item, and it failed again, so every workflow on the worker stalled.
