Improve test logging in GitHub CI (#2856)

This changelist reduces console noise and simplifies test logging artifacts in GitHub CI, including the following specific changes:

- Drop the `-VV` flag from the CTest invocation, so that verbose output is printed only for failing tests.
- Rename test log results to `TestLog_${{ matrix.name }}` for alignment across artifact names.
- Add `if-no-files-found: ignore` to the test log upload step, so that jobs without a test step don't generate warnings.
