Increase HTTP timeouts on CI (#8031)

Since we re-enabled HTTP API tests on CI (https://github.com/sigp/lighthouse/pull/7943) there have been a few spurious failures:

- https://github.com/sigp/lighthouse/actions/runs/17608432465/job/50024519938?pr=7783

That error is awkward, but running locally with a short timeout confirms it to be a timeout.


  Change the request timeout to 5s everywhere. We had kept it shorter to try to detect performance regressions, but I think this is better suited to being done with metrics & traces. On CI we really just want things to pass reliably without flakiness, so I think a longer timeout to handle slower test code (like mock-builder) and overworked CI boxes makes sense.
