[source_cell] parameter.h is widely used in source_cell's code

[Critsium-xy]

Describe the Code Quality Issue

The single most pervasive violation of the "source_cell should only depend on source_base" rule is the direct use of the global singleton PARAM (extern Parameter PARAM, declared in source_io/module_parameter/parameter.h). Instead of receiving configuration through function arguments, these files reach into the process-wide global PARAM.inp.* / PARAM.sys.* / PARAM.globalv.* directly, which pulls source_cell into a hard dependency on source_io. Because source_io in turn depends on source_cell in 118 files, this is also a genuine circular dependency.
