fix: Ensure integration tests properly trigger historical packet loading

The integration tests were failing because historical packets weren't
loading automatically. The tests needed to properly trigger the bounds
update event after the map initializes.

Changes:
- Add PostGIS location field to packet fixtures when lat/lon are provided
- Execute JavaScript to manually trigger bounds update after map loads
- This ensures the sendBoundsToServer function is called
- Adjusted timing to wait for map initialization before triggering

This should make the integration tests more reliable by ensuring
historical packets are loaded after the map is ready.
