fix: proof verifier exception

[jleach]

Summary of Changes

This PR addresses a bug where the connection associated with a proof request was being unintentionally deleted during the verification process. This deletion caused issues in other parts of the application that relied on the connection's existence, as the connection ID was still present in the proof record.
