fix: Cmd-K exchange selection reads exchangeId from URL params

ExchangesPage ignored the exchangeId URL parameter, so selecting an
exchange from the command palette navigated to the right URL but never
displayed the execution overlay. Now derives selection from URL params
as fallback, and LayoutShell passes selectedExchange in state for
exchange/attribute results.

+- Always use `@cameleer/design-system` CSS variables for colors (`var(--amber)`, `var(--error)`, `var(--success)`, etc.) — never hardcode hex values. This applies to CSS modules, inline styles, and SVG `fill`/`stroke` attributes. SVG presentation attributes resolve `var()` correctly.
