The previous implementation iterated find_each(&:revoke!) on both the
access-token and refresh-token associations. OidcAccessToken#revoke!
also cascades to its refresh tokens, so a chain of N access tokens with
their refresh tokens produced ~3N UPDATEs (outer loop + cascade +
outer refresh loop double-writing) all while holding a pessimistic
lock on the auth_code row. Replace with scoped update_all on each
association -- 2 UPDATEs total, no behavior change.
Also hoist the repeated refresh_token_record.oidc_authorization_code
lookup in the rotation path to a named local and drop the duplicated
inline comment.
