The timeout message interpolated the raw request URL, and
createFetchTracker records that message verbatim into the Network log
and the persisted session. An OAuth endpoint's query string can carry a
`code`, an `access_token` or a `client_secret` — exactly the fields
fetchTracking already redacts everywhere else it records a URL — so a
stalled signed endpoint would have written its secret to both.
Redacted with the existing `redactUrlQuery`, in the
OAuthRequestTimeoutError constructor rather than at each display site,
so both the message and the public `url` field are covered by
construction and no future consumer can reintroduce it. The route's own
proxied-timeout message and the URL in its 504 marker get the same
treatment, since both cross back to the browser and are recorded there.
The path and every non-sensitive parameter survive, so the endpoint
stays identifiable — which was the point of naming it.
