[FIX] mail: activity view: progress bar counters

The commit odoo@c877cab
has recently refactored the css of the kanban column progress bar making
the rules for o_legacy_kanban_counter be applied only in legacy kanban
views. This lead the style of the progress bars in activity view to be
broken. Here we fix that style by copying the rules we want in the
file activity_view.scss.
