Implement Chart Style Options Menu

[PauloMFJ]

Overview

Adds the chart-style options menu to chart cards, reachable from the card's action bar.

What's new

• MenuChartOptions — a radio menu (bar vertical / bar horizontal / line) with Cancel / Update, opened via the chart-options action and dismissible by Escape, backdrop, or Cancel.
• New icons: bar_chart_vertical, bar_chart_horizontal, line_graph_double; renamed bar_chart → bar_chart_outlined and line_graph → line_graph_single.

Refactor

• Each card variant (CardChart, CardText) now owns its own Card.Base — actions, content, footer, and (for charts) the menu — instead of the atlas shape assembling them. The shape just selects the variant and passes in id + content/state. Promotes - Card.Footer to a shared element.
• The chart-options action and isStyleMenuOpen live together in CardChart, so the button toggles the menu directly.

Code Review

This pull request refactors the card component architecture by shifting the responsibility of rendering actions, content, and footers from the shape utility down to the specific card variants (Card.Text and Card.Chart). It also introduces a new MenuChartOptions component to support switching chart styles. The review feedback highlights a few issues: a missing ref attachment on the dialog container which breaks the focus trap, a missing auto-close behavior when confirming a chart style, and a regression where an undefined card variant no longer falls back to rendering text.
