Move people to Unassigned when Product end date passes

[saur24]

Feature Request

As a user of PeopleMover
I want people on products that have a future end date to move to the unassigned section instead
so that people do not disappear if I forgot to move them before the scheduled product end date

Acceptance Criteria

Given a product with people on it has a future end date
When the date occurs
Then the people assigned to only that product should be moved to the unassigned column unless they have a scheduled assignment on that date
And everyone on the archived product should no longer be on it
AND this date should show as a purple circle on the calendar if reassignments occur

Given a person assigned to two different products
When the product end date occurs
Then we should continue the current behavior of NOT adding the person to unassigned since they already exist on a different product
And everyone on the archived product should no longer be on it

Accessibility Criteria

• Text and background color meets a minimum color contrast ratio of 4.5:1
