feat(icons): flipped route icon, added route-arrow-right icon (#4729)

* feat(icons): add route-arrow-right

Adds route-arrow-right: a serpentine route ending in an arrow, giving
the route a direction of travel.

route depicts a path between two waypoints but has no direction. This
reuses route's exact serpentine geometry (the 3.5-radius arcs at x6.5 and
x17.5, rails at y5/y12/y19, same 2px margins), replacing the waypoint
circles with a directional arrow that follows Lucide's arrow convention
(the shaft ends at the chevron apex, as in arrow-right).

Naming: happy to switch to route-arrow if a directional family isn't
wanted. A route-arrow-left mirror and a both-arrows variant are natural
follow-ups if this lands.

* Apply batched suggestions from code review
