Inplace volumes delta ensembles

[HansKallekleiv]

Adds delta ensembles to InplaceVolumesNew and InplaceVolumesTable.
The delta calculations is currently done in the frontend.
We can consider moving it to backend for performance in a later PR. Should be combined with some refactoring of the backend code.

• For a group containing one valid realization, Polars' sample standard deviation (std() with ddof=1) is undefined/NaN, but this returns 0. This makes client-computed delta statistics disagree with the regular statistical table for single-realization groups.

• For a group with exactly one finite realization, this returns stdDev = 0, but the backend uses Polars std() with ddof=1; that result is null and is converted to NaN (inplace_results_df_utils.py:191,254). Delta statistical tables therefore disagree with regular backend tables for singleton groups. Return NaN when count < 2 so the client-side aggregation actually matches the documented backend behavior.
