Adds the openapi blueprint branch in load_user_from_request so that
account-branch device-flow approval routes (approve / deny /
approval-context) can authenticate via the console session cookie
under @login_required.
Splits extract_access_token into two helpers:
- extract_console_cookie_token (cookie-only) — used by openapi
approval routes that must not fall through to the Authorization
header, where dfoa_/dfoe_ bearers live (those aren't JWTs and
PassportService.verify would crash on them).
- extract_access_token retains both code paths for legacy callers.
