In an upcoming RTL release, the MLKEM (ABR) key vault integration will fix a dword ordering issue, where dwords ordering was reversed with respect to the other cryptographic hardware (e.g., how MLDSA behaved).

I tested this against the upcoming RTL on the FPGA to confirm this behavior and modified the test firmware.

This will fail on FPGA until the bitstreams are updated.
