[arm64] Fix TestLeafNode unit test by ensuring proper node alignment
The following error occurs when running `bin/cbtree-test
--gtest_filter=TestCBTree.TestLeafNode` in an Rocky ARM environment.

Bus error
The TestLeafNode unit test was triggering SIGBUS crashes on ARM64
architectures due to unaligned access of atomic version fields.
This occurred because the test created LeafNode instances on the stack
without guaranteed alignment, while ARM64 strictly requires 8-byte
alignment for atomic uint64_t operations.
This test-specific fix complements the production code alignment
measures and ensures:
- Unit tests respect the same alignment requirements as production
- ARM64 environments don't trigger SIGBUS during test execution
- Test reliability across different architectures
Testing environment:
- ARM64 (Neoverse-N1) with Rocky Linux 9.5
- Docker container runtime
- Strict alignment enforcement causing SIGBUS on unaligned access
We extend our gratitude to Zoltan for his essential testing validation
and remediation recommendations in this fix.
