Inelastic Bayes Fitting interface refactor

[robertapplin]

Description

The code for the Inelastic Bayes Fitting interface could do with some refactoring to make it easier to test certain areas of the code, and to ensure that it is easier to maintain and extend in the future. The current code for the interface would be good to separate this out so the Qt framework is isolated from most of the logic in the code. We also want to reduce the reliance on the InelasticTab class.

This issue is an overarching issue which will be used to keep track of the refactoring for the Indirect Bayes Fitting interface that is required for the code to be in good shape.

Plan

• MVP for Inelastic Bayes Fitting interface #36374
• The AlgorithmRunner class should be used instead of the BatchAlgorithmRunner as it means we can avoid Qt connections in our presenter.
• The Bayes Fitting interface should also be made independent from the InelasticTab class as much as possible.
