Refactoring of js code base:

- Grouping js files based on the elements of the data model instead of parent js class
- All js files providing functionality for one element of the data model are now in one folder; this makes is easier to implement changes for one element in all affected files/ classes
- js files which are common to multiple elements are in the common folder
- The new structure is more in alignment with the new Go backend code base structure
- This commit does not contain any changes in functionality of the frontend
