these unused includes were identifier by clang-include-cleaner. after auditing these source files, all of the reports have been confirmed. please note, because quite a few source files relied on `utils/to_string.hh` to pull in the specialization of `fmt::formatter<std::optional<T>>`, after removing `#include <fmt/std.h>` from `utils/to_string.hh`, we have to include `fmt/std.h` directly.
