+ * Stat cards для webhook subscription detail. 4 status counters
+ * (pending / retrying / delivered / dlq) + computed success rate.
+ *
+ * <p>Implementation: 4 parallel React Query subscriptions с
+ * {@code size=1, page=0} per status — backend возвращает
+ * {@code totalElements} count'ом без heavy payload. Cheap, дешевле
+ * чем добавлять отдельный /stats endpoint backend.
+ *
+ * <p>Refetch piggybacks на cache invalidation которая уже работает
+ * (после retry / status filter changes). Поэтому без явного refetchInterval.
+ *
+ * <p>Phase B (followup): real-time bar chart per hour за последние 24h —
+ * требует /stats?bucketBy=hour endpoint в backend.
