Part of the GitLab a11y audit. Fixes keyboard and naming problems found in a full keyboard audit beyond the reported issues.

This PR:

• makes menus, confirmation dialogs and the "Add chart" popover keyboard operable
• makes time sliders and time range brushes keyboard operable
• makes the rich text editor, color palette select and color picker keyboard operable
• adds names to icon-only buttons, selects and editors
• adds a "Skip to main content" link

How to test

1. In the chart editor, open the chart actions menu with Enter and use the arrow keys; delete a chart and confirm with the keyboard.
2. Open a color field and pick a palette and a custom color using only the keyboard.
3. In a text field, use the toolbar with the arrow keys, add a link, and Tab out of the editor.
4. Run npx playwright test e2e/keyboard-widgets.spec.ts.
