feat(admin-web): surface monitoring platform authorization status

Dashboard and question-detail views now read platform_authorization_status
from the API. Tracking disables collect-now when the account has no
desktop client, no authorized platforms, or the selected platform is
unauthorized, and keeps the six-platform matrix stable; question-detail
replaces tabs and cards with an explicit unavailable notice when the
account is not authorized for monitoring. Adds the shared type and
en/zh strings covering each status.
