feat: Cmd+K Enter applies full-text search to dashboard

When pressing Enter in the command palette without explicitly selecting
a result (via arrow keys or mouse), the search query is now applied as
a server-side full-text filter on the Dashboard table. Explicit
selection still navigates to the exchange. Updates design system to
v0.1.18 for the new onSubmit prop.
