Routing tasks 737-741 have swapped coordinates in expected URLs

[vishaalram02]

Summary

The expected URL patterns have destination;origin but OSRM API format is origin;destination.

Example: Task 737

Intent: "View the route from Carnegie Mellon University to Philadelphia 76ers stadium"

	Coordinates	Order
Expected	-75.17...;-79.94...	Philly→Pittsburgh ❌
Agent	-79.94...;-75.17...	Pittsburgh→Philly ✅

Fix

Swap coordinates in assets/dataset/webarena-verified.json for tasks 737, 739, 740, 741.

Example fix for task 737:

- "expected": {"url": "^.*/route/v1/.*/-75.1718916,39.9011873;-79.9427192,40.4441897.*$"}
+ "expected": {"url": "^.*/route/v1/.*/-79.9427192,40.4441897;-75.1718916,39.9011873.*$"}

This issue affects tasks 259, 265, 737, 738, 739, 740, 741 in the hard task subset.
