crosstyan 29c8ef3990 fix: fix the timestamp precision error cause the jax version not giving the correct result

Epoch timestamps are ~1.7 × 10⁹; storing them in float32 wipes out
sub‑second detail (resolution ≈ 200 ms).  Keep them in float64 until
after subtraction so we preserve Δt‑on‑the‑order‑of‑milliseconds.

- Introduced a `_DEBUG_CURRENT_TRACKING` variable to track the current indices of tracking and detection during calculations.
- Added a `_global_current_tracking_str` function to format the current tracking state for debugging purposes.
- Enhanced `calculate_distance_2d` and `calculate_tracking_detection_affinity` functions with debug print statements to log intermediate values, improving traceability of calculations.
- Updated `perpendicular_distance_camera_2d_points_to_tracking_raycasting` to accept `delta_t` from the caller while ensuring it adheres to a minimum threshold.
- Refactored timestamp handling in `calculate_camera_affinity_matrix_jax` to maintain precision during calculations.
