[beacon] Remove last uses of dkg_v0 (#20113)

## Description 

Switching old code to the v1 structs (should be safe since that data is
not being used anymore).

## Test plan 

How did you test the new or updated feature?

---

## Release notes

Check each box that your changes affect. If none of the boxes relate to
your changes, release notes aren't required.

For each box you select, include information after the relevant heading
that describes the impact of your changes that a user might notice and
any actions they must take to implement updates.
