Revisit `maxPrecedingRecords` default in (modularized) `ConsensusConfig`

In PR #7983 we modified the `maxPrecedingRecords` default to be 950 instead of 3. However, there is a question of whether this new value is acceptable when there are only 1000 nanos (in theory) available for preceding records. We need to verify that either this value is acceptable and the app still works correctly, or that we need to change this config back to 3 and figure out a different way to create preceding genesis records.
