fix: Center integration tests on test packet locations

The integration tests were failing because the map was loading at a default
location that didn't include the test packets. The tests were creating
packets in specific locations but the map view wasn't centered on them.

Changes:
- Center first test on New York area (40.735, -73.996) where test packets are
- Center other tests on central US (39.8283, -98.5795) for broader view
- Add appropriate zoom levels for each test scenario
- Ensure all test URLs include location parameters

This ensures the test packets are within the map viewport when the tests
run, allowing the markers to be visible and clickable.
