refactor(chart) :: import and use 3rd party ApexCharts types

[81reap]

apexcharts.ts now has one implicit any, TooltipArgs keeps its w: any until upstream ApexCharts updates it's tooltip types.

Fixing this smoked out six workarounds ::

1. options as ApexOptions hid that zaxis is not an ApexCharts option at all.
2. yasix has to be normalized into an array and forwarded within bubbleTooltip. Now chartTooltip takes the axis titles directly.
3. formatTooltipX returned a value where tooltip.x.formatter is declared to return a string.
4. pie labels were (string | number)[] where ApexOptions wants string[].
5. xaxis.tickAmount was assigned after the literal instead of inside it.
6. the dataLabels formatters destructured an opts that ApexCharts declares optional, so they are now three named functions.
