When fewer than 9 valid realizations exist at a time step, the linear
interpolation percentile formula has no valid result for P10 and P90.
Previously HUGE_VAL (inf) was returned. Now clamp to min/max of the
available sorted values instead, avoiding inf in plotted curves.
Replaced all references to RiaStatisticsTools with RigStatisticsTools across the codebase, including header includes, static method calls, and test files. Updated CMake configuration to remove RiaStatisticsTools and add RigStatisticsTools. Renamed and updated related unit tests. No changes to logic or algorithms; this is a namespace and organizational refactor for consistency. Also added ApplicationLibCode include directories as PRIVATE to relevant targets.
* Refactor and extend percentile calculation utilities
Refactored percentile and quantile calculation logic for improved flexibility and maintainability. Added helper functions for quantile/percentile validation, introduced a new vector-based calculatePercentiles method, and updated calculateStatisticsCurves to use it. Refactored nearest-rank and interpolated percentile methods to accept percentiles as vectors and improved parameter validation. Enhanced documentation throughout and updated function signatures in the header for clarity.
