fix(sync): retry cleanup on Access -1102 lock contention

ACE ODBC reports lock contention ("无法更新；当前被锁定。(-1102)")
as a generic pyodbc.Error (HY000), NOT pyodbc.OperationalError, so the
old except clause never caught it and gave up after the first collision
— making cleanup_lock_retries:3 a no-op for the 氩弧焊/高写入库 -1102 case.
Now catch pyodbc.Error and retry only on lock messages ("被锁定"/"-1102"),
re-raising other errors immediately instead of retrying them 3×.
