Minor fixes for load balancing and stateless simulations

[Snapex2409]

Load Balancing:

Added an implicit coupling iteration counter to determine the frequency of load balancing.

ModelManager:

Fixed the ModelWrapper for stateless simulations. Without the name property, it would return an incorrect class name during lookups.

Interpolation:

Fixed RBF basis functions. (brackets were placed incorrectly)
Fixed RBF interpolation domain selection. (mixed up tree height and depth)
Fixed interpolation normalization. Normalization scaling is now based on a fraction of the input and not constant.

Adaptivity:

Fixed data size extraction of micro simulation input and output during adaptivity interpolation for empty micro manager ranks.

Checklist:

• I made sure that the CI passed before I ask for a review.
• If this is a use-side change, I added a summary of the changes (compared to the last release) in the CHANGELOG.md. If this is a breaking change, I wrote breaking change at the end of the changelog entry.
• If necessary, I made changes to the documentation and/or added new content.
• I will remember to squash-and-merge and provide a useful summary of the changes of this PR.
