Refactor positioning calculation and relocate node sizing methods

This commit modifies positioning logic, specifically the calculation of offsets and pin locations. Methods for retrieving the widest and tallest children from a list of nodes were moved from `passive_stack_transformer.dart` to `utils.dart` for better organization and easier code reuse. New checks were introduced in `freeform_decorators.dart` to prevent illegal positions outside parent bounds in wrapped nodes. Other minor changes were made in several files to accommodate these primary changes.
