RFC 6749 5.1 defines an omitted `scope` in a token response as a grant
identical to what was requested, and `resolvePersistedScopeAfterGrant`
already encodes that rule -- but the ordinary authorization leg never
gave it a `requestedScope` to fall back to, so nothing was persisted and
the previous stored scope kept being reported as what the current token
carries.
`authenticate()` now records `provider.scope` as the pending
authorization scope once the authorization URL has been captured, so it
survives the redirect and reaches `completeOAuthFlow`. The
enterprise-managed leg had the same defect for the same reason and is
fixed one level up: it now falls back to `scopeForMint`, which is what
the mint actually asked for, rather than to the raw
`pendingAuthorizationScope` that is undefined on this leg.
A response that does carry `scope` still wins over the request, on both
legs.
