DB and config for sbnd gen2 data

[francois-drielsma]

Thanks for this contribution. We have prototyped the integration on pr31-prototype (commit 05930ab) with the following structure:

• The default SPINE release moves to v0.17.1.
• The two full configurations and bundled calibration files are replaced by a versioned data:260501 modifier.
• The lifetime and YZ maps are read from $SBND_DATA_DIR/v01_42_00 rather than copied into this repository.
• The modifier applies the requested gain, lifetime database keys/scale, and YZ correction inside the model, before segmentation.
• Compatibility is split at 260501: the new modifier requires model/post configurations with in-model calibration, while older data modifiers require configurations with post-processing calibration.

We have not carried over the no-calibration configuration yet. Could you clarify its intended use? Is it needed for a specific production output, or is it primarily an A/B validation against the newly calibrated processing?

Would the current single production data modifier be sufficient? If the uncalibrated comparison is required, we can add an explicitly named data_nocalib modifier once the use case is clear.
