[FIX] *: replace incorrect `view_mode`

Some actions were using `list` as value for the attribute `view_mode`.
This value is not valid, the list view is named `tree` server-side.

This was causing issues when setting `view_ids` (`ir.actions.act_window.view`)
on the action because `tree` and `list` were not matching correctly.

Closes #21056
