feat: use standalone Filter in assignmenents modifications

[TheMaskedTurtle]

PR Summary

Starting the migration of modification so that they can really be standalone. Starting by inheritors of AbstractAssignmentModification which are ByFormulaModification and ModificationByAssignment.

For that I had to:

• Create a new data structure that is based only on Filter interface
• Modify dto to modification mappers to use FilterLoader and build modifications with Filter interface
• Adapt modifications application so that it matches the new data structure
• Adapt tests

Also, reports were not used properly towards the ReportNode interface, I adjusted that as well in the related classes.
