Fix dashboard header layout — center worker orbs, reposition quick-nav

Worker orbs now centered across the full header width instead of
right-aligned. Watchlist/Wishlist buttons moved to absolute top-right
corner in their own container, preventing tooltip overflow from pushing
them to a second line. Import button removed from header (accessible
via sidebar).

Responsive: at 900px quick-nav drops to static full-width row, worker
orb tooltips hidden on mobile (status visible via orb color/spinner,
details on Tools page). At 768px everything stacks vertically.
