hailin 49949ff979 fix(mining): use unified transaction to prevent timeout errors ... - Wrap all database operations in executeSecondDistribution with UnitOfWork.executeInTransaction - Pass transaction client to repository save methods - Use longer transaction timeout (60s) for batch operations - Move Redis operations outside transaction (non-ACID) - Add distributeToSystemAndPendingInTx method that accepts tx client This resolves the "Unable to start a transaction in the given time" error caused by multiple concurrent transactions competing for database connections.
