[FIX] stock: date field on move line after `_action_done`
[FIX] stock: date field on move line after `_action_done`

We make the date field behaves similarly to the date field on the stock
move line: before `_action_done` is called, it is the created date,
after, it is the date done.

Note that this field is only used in a report of the stock move lines.

Fixes #23725
