feat(tui): multi-row color-coded sparkline chart with Y-axis

Replace ntcharts with custom multi-row sparkline. Each bar is color- coded by latency threshold (green < 200ms, yellow < 500ms, red > 500ms) and DOWN checks render in red. 3 rows tall with 24 discrete levels. Y-axis labels (max/min ms) on the left, Min/Avg/Max stats below. Zero external dependencies — removed ntcharts.
