refactor(rc): replace hard‑coded version fields with version.h macros

Adds `#include "version.h"` and replaces all numeric and string version
literals in ColorCop.rc with `VER_FILEVERSION`, `VER_PRODUCTVERSION`,
and their corresponding string macros. This centralizes version
definition, keeps the About box and VERSIONINFO block in sync with the
generated version.h, and removes the last remaining hard‑coded 5.5.7
values.
