redactURL's fallback returned the raw string when url.Parse found no host.
A scheme-less BaseURL (127.0.0.1:9880/v1?token=...) fails to parse, so the
signed query reached the WARN log and the error chain verbatim. Strip at
? and # in that path, keeping the '@' full-redaction rule first.
Test pins the scheme-less query/fragment cases and goes red if the fix
is reverted.
