Add ability to toggle showing deleted Users

User Story:

• As a center admin

• I want to have a toggle in User screens with the title "Show deleted users" disabled by default

• So that I can decide if I want to see deleted users or not in the table.

​

Acceptance Criteria:

Scenario 1:
Given that I am on the User screens as a center admin,
When I enable the "Show deleted users" toggle,
Then I should see both active and deleted users in the table.

Scenario 2:
Given that I am on the User screens as a center admin,
When I disable the "Show deleted users" toggle,
Then I should only see active users in the table, with deleted users being hidden.

**Scenario 3:
**Given that I am on the User screens as a center admin,
When I first access the screen,
Then the "Show deleted users" toggle should be in the disabled state by default.
