fix: updates for SafePassword API change (#4927)

Description
---
Minor updates for a corresponding [change](tari-project/tari_utilities#52) to the `SafePassword` API.

Motivation and Context
---
A pending change in `tari_utilities` to the handling of sensitive data includes a new implementation of `SafePassword`. One change removes derived traits for equality testing in favor of equality testing on references to the underlying passphrase data. This work makes the minor but necessary changes to address this API change.

How Has This Been Tested?
---
Tests pass after applying the linked `tari_utilities` PR. Note that tests will pass using the current `SafePassword` API as well, as the dependency change PR restricts the API.
