Every data change went through renderChart, which rebuilt the chart from a
full option set: animations restarted and zoom/selection state was lost.
Add an updateData path that patches the live chart via ApexCharts'
updateSeries (and updateOptions only when categories/labels actually
change), exposed as AxisChart.updateData / PieChart.updateData. Before the
first render there is nothing to patch, so those fall back to setData.
The theme overlay is re-applied to the merged options, so a rebuild after
a detach starts from the patched data.
