Support forecasting columns (_yhat, __yhat_upper, __yhat_lower) with dimensions in charts

What is the problem or goal the end user is trying to solve or accomplish?

Users want to use forecasting/prediction columns (_yhat, __yhat_upper, and __yhat_lower) in charts that include dimensions. Currently, the series name detection only works with "ends with" logic, which prevents these prediction columns from working properly when dimensions are present.

How are they solving it currently?

Users are limited to using these forecasting columns only in charts without dimensions, or they have to work around the limitation by restructuring their data or using separate charts.

What is the recommended solution by the Customer?

Change the series name detection logic from "ends with" to "contains" for forecasting columns (_yhat, __yhat_upper, __yhat_lower). Additionally, prevent the shaded confidence interval areas from stacking inappropriately.
