Restore single-arg copy_history support

This now uses parse_db_tb_args, which requires exactly two arguments (database, table). Before this change, copy_history('t') defaulted to the current database and even allowed copy_history('db.table'); with the new signature those existing usages (including the test tests/sqllogictests/suites/mode/cluster/distributed_copy_into_table.test using copy_history('t')) will raise BadArguments, breaking backward compatibility for users and CI. Consider accepting one argument and defaulting to the current database (e.g., via parse_db_tb_opt_args or explicit fallback) while still parsing the optional /branch suffix.
