tests: suppress GCC 16 false positive -Warray-bounds warning

Browse Source 
GCC 16 emits a spurious -Warray-bounds warning when std::make_shared
uses placement new into its internal control block buffer. This causes
build failures in client_zero_test.cpp and mb_controller_test.cpp.

Suppress the warning with #pragma GCC diagnostic around the affected
std::make_shared calls, guarded by __GNUC__ >= 16 to leave older
compilers unaffected.
