chore(feature-activation): improve phased testing logs

[glevco]

Motivation

During the Feature Activation Phased Testing on testnet, we noticed that logs were missing the block hash, which makes it harder to search for specific logs.

Acceptance Criteria

• Add block hash to Feature Activation Phased Testing logs.

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
