feat(admin-web): extract AI account management into its own page

Move the AI-platform account status cards out of TrackingView into a
dedicated AIAccountsView, registered at /tracking/ai-accounts with a nav
entry and route/nav i18n strings. Keeps the tracking dashboard focused
while giving accounts, authorization state and desktop runtime nodes a
first-class page.
