Check optionals in tidy

clang-tidy-18 makes this feature stable enough for us to use in general.
Enable the check, and fix the couple of regressions that have snuck in
since we last ran the check.

Tidy seems to not be able to understand that ASSERT will not continue,
so if we ASSERT a std::optional, it's not a bug.  Add explicit checks to
keep tidy happy.

Tested: clang-tidy passes.
