ci: Update Clang in "tidy" job

This change switches to the latest IWYU 0.23, which is compatible with
Clang 19.

Fixed new "modernize-use-starts-ends-with" warnings.

The new "bugprone-use-after-move" warning in `result_tests.cpp` is a
false positive caused by a bug in Boost.Test versions < 1.87. This has
been addressed by introducing a local variable.
See upstream references:
 - Issue: boostorg/test#343
 - Fix: boostorg/test#348
