Ubuntu 26.04 moved ubuntu-latest to GCC 15 and clang-tidy 21, exposing one Werror array-bounds diagnostic and three analyzer warnings. Size Decimal32 test buffers to cover inlined branches, use bounds-checked access in view tests, and make integration file reads check seek, size, and read failures.

Verified locally with GCC 15.2: CMake IPC/test build, 409 tests, and clang-tidy 21 for the affected targets.
