AI Summary: This issue proposes refactoring function calls in Fortran code. It aims to consolidate numerous individual arguments into structured `config` and `model_args` objects, reducing the argument list for functions like `init_cont`. The task involves modifying the subroutine definitions to access values from these objects and updating all corresponding call sites for `init_cont`, `radfunction_dens`, and `radfunctions_dist`.
