Two check-source-text / clang-tidy fixes on the MC/DC test files: * Wrap error-code comparison operands in WC_NO_ERR_TRACE() (check-source-text check I). Code comparisons (blake2b/blake2s/hpke white-boxes and the logging global-queue pull check) are wrapped; the pseudo-code in doc comments and the WB_CHECK message strings (mcdc_fault_alloc.h, dsa/mlkem fault white-boxes, logging white-box) are reworded so an error code is no longer adjacent to == / != . * Uppercase the integer-literal suffixes in test_sakke.c (384u -> 384U, etc.) for clang-tidy readability-uppercase-literal-suffix. No behavioral change.
