L40S (48GB) and H100 (80GB) have plenty of headroom; the 2GB cap was a
conservative leftover that tripped on workflow zgjgc with 17.8M imbalance
bars (3.2GB). 8GB budget leaves ~28GB free on L40S after model + activations
+ workspace.
Updates both call sites:
- DqnGpuData::upload_slices (training data, the failing one on zgjgc)
- PpoGpuData::upload (market data, same constant)
Error message format strings updated 2.0 GB → 8.0 GB.
