let the router decide which nav item is active

Dock, Header and the mobile sheet were computing active state from
useLocation with two copies of the same startsWith helper. react-router's
NavLink already knows. end is set for Home only: without it NavLink treats
'/' as an ancestor of every route, and with it on the others a detail route
would lose its highlight.

Segment matching is stricter than the string prefix it replaces, which is
what was meant all along.
