fix: prevent tokio runtime deadlock in credential issue/verify
The credential issuance and verification handlers used Handle::block_on() directly inside the tokio runtime, causing a deadlock. Wrapped with block_in_place() to properly yield the runtime thread. Also completed full feature verification across all 25 test groups (~175 checks) on live server. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
