PR Summary

Medium Risk
Although the code change is tiny, it intentionally breaks compatibility for existing full-archive block storage versions and can force node operators to re-sync or migrate data.

Overview
Updates the storage compatibility gate by bumping STORAGE_VERSION_BLOCKS from 6.0 to 7.0, causing StorageScope::FullArchive databases with the previous blocks version to be treated as incompatible (or require reinitialization/resync) when opened.

Replaced with migrator approach instead of major version bump.
