fix(argo): switch sanitizer/nsys templates to training-data-pvc (full 27 months)

The test-data-pvc only had 3-4 months of MBP-10 (Q1 2024 only), causing
walk-forward fold generation to fail with 'Need at least 10 months of data'.
Production training uses training-data-pvc mounted at /data with subdirs
futures-baseline / futures-baseline-mbp10 / futures-baseline-trades —
that's the full 27-month dataset.

Switching all three env vars (FOXHUNT_TEST_DATA, FOXHUNT_MBP10_DATA,
FOXHUNT_TRADES_DATA) and the volume/mount to point at the production
data PVC. multi_fold_convergence's 6/2/2 walk-forward (10 months min)
now has ample data.
