The std::ranges view conversion (excluded on MinGW because of its incomplete C++20 ranges support, #4916) was gated by the same #if JSON_HAS_RANGES && !defined(__MINGW32__) condition at seven independent sites in to_json.hpp and type_traits.hpp, with the MinGW rationale duplicated in two of them and missing from the rest. Since the sites come in matching pairs (one enables is_compatible_range_view and a view-based overload, the other adds the exclusion to the plain-array-type overload), a drift between any pair would produce an ambiguous or missing overload on exactly one platform. Add JSON_HAS_RANGE_VIEW_CONVERSION next to JSON_HAS_RANGES in macro_scope.hpp, combining both conditions with the #4916 reasoning in one place, #undef it in macro_unscope.hpp, and use it at all seven sites. This does not fold the MinGW check into JSON_HAS_RANGES itself: JSON_HAS_RANGES is user-overridable and also gates the enable_borrowed_range specialization in iteration_proxy.hpp, which is not excluded on MinGW. No behavior or public API change: JSON_HAS_RANGE_VIEW_CONVERSION expands to exactly the condition that was previously written out at each site. Overlaps #5585, #5600 and #3575, which touch the same to_json.hpp and type_traits.hpp lines; the change here is a mechanical search-and-replace of the guard condition and should rebase cleanly.
