Earlier <tree>→<list> pass missed the ir.actions.act_window.view_mode field.
Clicking the Family Law Cases menu raised "View types not defined tree found
in act_window action 549" in the Odoo 18 client.
Updated all 17 view_mode declarations across 12 view files (tree→list,
preserves kanban/calendar/form pieces).
