before this change, we rely on the default-generated fmt::formatter created from operator<<, but fmt v10 dropped the default-generated formatter. in this change, we define formatters for `gms::application_state`, but its operator<< is preserved, as it is still used by the generic homebrew formatter for `std::unordered_map<>`.
