docs: correct and reformat the chart style property tables

The tables listed eight properties no rule reads any more, omitted
eleven that exist, and gave --lumo-* variables as default values in a
release whose default theme is Aura. They were also the last tables
under articles/components/ still using the Default Value column that
every other styling page dropped for Supported by.

Switch to the standard format, which removes the stale defaults along
with the need to maintain any of them, and correct the membership. The
per-theme differences move into prose above the tables, where they don't
have to be repeated per row.

Keep the vaadin-chart {...} selector and say why it isn't html {...}:
Lumo declares most of these properties on the chart element, so a value
inherited from html never applies. Verified in the browser against Aura,
Lumo and no theme, along with every property listed and every one
removed.

 == Style Properties
 The following style properties can be used in CSS stylesheets to customize the appearance of this component.
 
-To apply values to these properties globally in your application UI, place them in a CSS block using the `vaadin-chart {...}` selector.
+Apply them in a CSS block using the `vaadin-chart {...}` selector, or a CSS class name on the chart.
+Unlike other components, they can't be applied from an `html {...}` block.
+The Lumo theme sets most of them on the chart element, and an inherited value doesn't override that.

 See <<{articles}/styling/styling-components#component-style-properties,Component Style Properties>> for more information on style properties.

+The chart's own styles read these properties, so they work with the Aura theme, with Lumo, and with neither.
+The themes differ in what they set by default.
+Aura makes the plot background transparent and restyles the range selector buttons.
+Lumo gives most of the properties a `--lumo-*` value, and is the only theme with chart
+<<{articles}/components/charts/styling/#theme-variants,variants>>.
+
+// Theme defaults live in aura/src/components/charts.css and
+// vaadin-lumo-styles/src/components/chart.css in the web-components repository.
