Copilot round 4 (one suppressed finding, and a real bug).
`extractSecretsFromStored` rebuilt the stripped `oauth` object from an
allow-list of the non-secret fields. That list had gone stale: it never named
`onInsufficientScope`, so a server carrying both a client secret and a
non-default SEP-2350 policy silently lost the policy on save, falling back to
`reauthorize`. This predates #2018 — the PR only extended the same list with
`authorizationParams` — but the list is the defect, so fix the class rather
than add a third entry to it.
The stripped entry now subtracts the one secret instead of enumerating what to
keep, so any field added to `oauth` later is preserved by construction.
Regression test verified to fail against the allow-list version:
`expected { clientId: 'cid' } to deeply equal { clientId: 'cid', onInsufficientScope: 'throw' }`.
