Ember Test Audit flaky tests

Ember Test Audit detected these flaky tests on main:

• Acceptance | task group detail: /jobs/:id/:task-group second breadcrumb should link to the job for the task group
• Integration | Component | TopoViz: clicking on an allocation in a deeply nested TopoViz::Node will associate sibling allocations with curves
• Integration | Component | TopoViz: when the count of sibling allocations is high enough relative to the node count, curves are not rendered
• Integration | Utility | exec-socket-xterm-adapter: resizing the window passes a resize message through the socket
