[FIX] crm: add filter for overdue opportunities

With commit[1], we introduced a feature that from the sales team, we can
see the overdue opportunities for a particual teams. However, the filter
that we use for related action which is supposed to show overdue opportunities
is not not added, and the filtration is not working as expected, showing us
all the opportunites for a team.

This commit fixes the issue by adding the invisible filter with proper
domain set within opportunities' search view and thus enables us to
filter overdue opportunites.
