ZgwHttpClient interpolated the full request uri and up to 500 characters of
the response body into its failure message. That message is persisted as
Aanvraag.ZgwError in SQLite and written to the log, and both halves can carry
a BSN: ZGW filters travel as query parameters (the citizen-scoped zaken list
filters on rol__betrokkeneIdentificatie__natuurlijkPersoon__inpBsn), and
OpenZaak echoes the offending request in its error bodies, so a rejected POST
/rollen comes back holding the owner BSN it was sent.
All three interpolation sites now use Redact(url) — the path without its
query — and the body snippet is replaced by the reason phrase. Status plus
path still routes a failure to the right endpoint; the lost detail already
has a deliberate home in ZGW_DEBUG_HTTP=1 (ZgwDiagnosticHandler), which is
opt-in, dev-only and not persisted.
The new test fails the one call in the fixture whose url carries a query
string and asserts the persisted ZgwError has neither the body snippet nor a
"?", while keeping the path and the 503. Verified red without the fix.
