test(evals): accept the rendered task link the UI redirects to its own company

The chat renderer writes the agent's /BIR/issues/BIR-1 link as
/RUN/issues/BIR-1, and the task page redirects a wrong-prefix link to the
task's company. Accept either prefix for the foreign task's link, and have
verifyResult follow it and wait for the task's own company route.
