Changing teams when on Brokers page not going to overview

### Current Behavior

When you are on the Team Broker page of one team, then use the team switcher to go to another team, you are taken to the Add Broker page of the second team (even if they have brokers defined).

The expectation when switching teams is to always be taken to the Overview page.

My guess is some of the unmount handling of the broker page is kicking in redirect logic and interfering with the top level redirect.

### Expected Behavior

_No response_

### Steps To Reproduce

1. Open the Brokers page of Team A
2. Switch to Team B - expect to be taken to the Team Overview page
3. Find yourself on the Add Broker page of Team B
