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.
