feat(dashboard): unify desktop header with the planner toolbar style

Brings the dashboard header in line with the Bookings/Lists/Budget/Files
toolbars: a single rounded bg-tertiary bar that groups the title, the
active/archived trip counters, and the view-toggle + widgets + new-trip
actions. Added a border and light shadow so the bar stands out against
the dashboard background in both light and dark mode. Mobile header is
untouched.
