Add manual expectations list for an inject

[RomuDeuxfois]

Problems to address

Currently, expectations are only partially designed in OpenEx (finding a simple flag, reading a document, manual check required). Expectations are not customizable and cannot be described with details to help the animation team evaluate players.

Use case

Every stimuli can have 0 to N expectations.

Each expectation have a title, a description and a score,

In Inject, it is possible to choose predefined expectations or create new one

When an expectation is validated, its score is added to the inject’s current score.
