Subject: Show a scheduled-vs-available indicator on the web timeline's Today
 section

Task 11 of the task-budgets-and-availability plan: reuse the
computeBudgetStatus helper (Task 8) in HandleTimeline so the dashboard's
Today section header shows scheduled/available minutes when a
budget-tracked task exists.
