This PR updates the deduplication logic in the get_collections_with_new_data method of rust/log/src/grpc_log.rs to sort by both collection_id and first_log_offset before deduplication, matching the logic used elsewhere in the codebase. Only the sort and dedup key are modified; no other logic is changed.
