[FIX] web: list: call mounted on subcomponents at reload

Issue was spotted in list views containing the "badge" widget with
decorations (e.g. in the Purchase Order list view). At first, the
decorations were correctly applied, but they weren't anymore after
a reload (e.g. after toggling a filter).

They weren't because the list renderer didn't called
'on_attach_callback' on its subwidgets at reload (thus, 'mounted'
wasn't called on its subcomponents, and the decorations are applied
in the mounted hook).

This commit moves the logic from the FormRenderer to the
BasicRenderer, so that it applies on List, Kanban, and Form views.

This commit also removes the transition scss rule on the badge
field widget as it caused a flickering at reload.

Task 2336440

closes odoo/odoo#57762
