Move app-owned redesign selectors into component styles.

The settings navigation and panel-layout rules style regular application controls from index.css. Add the styling in the owning components, or expose a shared variant or slot for these controls. Keep global CSS for generated Markdown, imperative DOM, runtime theme variables, animations, and integration styles.

As per path instructions, apps/web/src/**/*.{tsx,css} must follow docs/internals/web-ui.md, which reserves global CSS for cases component classes cannot express.

Also applies to: 1532-1545

Review comment at @apps/web/src/index.css around lines 1310 - 1315:
Move the app-owned settings navigation and panel-layout styling from global
index.css into the components that own those controls, or expose a shared
variant or slot for them. In particular, relocate the [data-settings-nav] and
[data-sidebar="menu-button"] redesign rule; keep global CSS only for the
documented exceptions.
