fix: show last tick suppressed count instead of cumulative history

Replace goal manager suppression badge (which grew unboundedly) with
lastTickSuppressedCount — the number of candidates suppressed in the
most recent tick. Stored in a module-level variable, exposed via the
goal-manager API, and displayed in the dashboard.
