perf: Index pick list field in stock entry and DN (#35738)
We check if pick list is created against them but there's no index so we
end up reading entire table.

```
+------+-------------+------------------+-------+---------------+----------+---------+------+--------+-----------+----------+------------+-------------+
| id   | select_type | table            | type  | possible_keys | key      | key_len | ref  | rows   | r_rows    | filtered | r_filtered | Extra       |
+------+-------------+------------------+-------+---------------+----------+---------+------+--------+-----------+----------+------------+-------------+
