Gennaro Prota db67ad3fd6 Align to_static_[w]string() with C++26 std::to_[w]string() ...

C++26 specifies that std::to_string() and std::to_wstring() format
floating point values as if using std::format(). This commit updates the
internal conversion helpers to match that behavior, using
std::format_to_n() for efficient, allocation-free formatting directly
into the static_string/static_wstring buffer.

Fallbacks using snprintf()/swprintf() remain active for pre-C++26
builds.

This ensures consistent formatting across standard and Boost APIs.
