Create AllSchedulesRoot and AllSensorsRoot, reusing display code from the existing Instance tabs. When the nav changes are launched, we can remove those tabs from that page and refactor this a bit.
Enable simple nav, click on "Schedules" and "Sensors". Verify proper rendering and behavior. Navigate to individual schedules and sensors, verify that the nav items are appropriately highlighted.
looks good - can you make sure the test plan includes unloadable schedules/sensors as well? easiest way to test is to turn one on and then change the repository name while it's still on.
