Link Port to Sea Network

How the routing works

1. Each port is linked to one or more nearby sea nodes (waypoints).
2. Sea nodes are connected by sea edges with a nautical-mile weight.
3. The calculator runs Dijkstra's algorithm on this graph from origin's nearest node to destination's nearest node.
4. The resulting polyline is rendered on a Leaflet map so the route follows water, not land.
