Yuzviak f66b266219 style(e2e): ruff auto-fix import sorting in coord + vpair + tests
Four I001 violations surfaced when running ruff over the full src/
tests/ tree (the CI command) rather than just the testing subpath:
- src/gps_denied/testing/coord.py
- src/gps_denied/testing/datasets/vpair.py
- tests/e2e/test_coord.py
- tests/e2e/test_vpair_adapter.py

All auto-fixable; no behavioural change.
