Pull request overview

This PR expands the C++ integration test coverage for the AZIHSM native RSA sign/verify APIs, adding additional negative-path and edge-case scenarios for both one-shot and streaming flows.

Changes:

• Add one-shot RSA sign/verify negative tests (tampered/truncated/empty/oversized signatures, wrong key usage, wrong hash algorithm).
• Add RSA-PSS-specific coverage (mismatched PSS parameters, invalid digest length for pre-hashed PSS, salt length boundary cases, determinism/non-determinism checks).
• Add streaming state-machine and edge-case tests (small output buffer on finish, empty input/chunk behavior, update/finish after finish).
