Expert-only track-time accessor that re-derives the HGTD track time from the per-layer cluster decorations (HGTD_has_extension, HGTD_cluster_time, HGTD_cluster_truth_class, HGTD_primary_expected), applying its own last-hit, time-consistency and minimum-hit selection.

For expert studies and internal validation only – see the warning in HGTD_Analysis/IHGTD_ExpertTrackTimeAccessor.h.

TODOs:

• values in lastHitIsOnLastSurface need to be confirmed for 21.9
• the 2-hit cut in the problematic PP1 region needs to be re-evaluated
• test if in the 1-hit case, a check of the spatial chi2 might help
