dashboard: refocus command palette search on submenu switch (#55401)

In the command palette, switching submenus — drilling in/out of a nested view or jumping via a breadcrumb by mouse — could leave keyboard focus on the clicked row or breadcrumb rather than the search input, forcing the user to click back into it before typing. The search input stays mounted across page changes, so this refocuses it in the `pushPage`/`popPage`/`goToDepth` handlers (alongside where they already clear the search) so the user can keep typing after every submenu switch.
