Rename "Active Realizations" (in UI) to "Realizations to Run"

Is your feature request related to a problem? Please describe. When setting up/running an experiment, the "Active realizations" label could be clearer.

Describe the solution you'd like Rather call the label "Realizations to run" Discuss with the team - this is a "big change" from an optical perspective - and should some of the CODE behind also change? Or is Active realizations a meaningful term "when actually running and analyzing", since it can be both "chosen not to run" or "failed" etc..
