test(e2e): rewrite VPAIRAdapter for real sample format
Real VPAIR sample layout differs from the prior speculative adapter: - poses_query.txt (not poses.csv) with ECEF xyz + Euler roll/pitch/yaw - no native timestamps — synthesised at 5 Hz - PNG images referenced by relative filepath Adapter now uses coord helpers (ecef_to_wgs84, euler_to_quaternion). Test fixture and conftest skip-reason updated to match. Integration test xfail condition extended to cover large ATE values when VO+GPR is not yet tuned for 300-400m nadir aerial imagery.

- Euler (roll, pitch, yaw radians, ZYX aerospace) → quaternion.

- Timestamps synthesised at 5 Hz (200 ms period) based on row order,
