Describe the feature

We can just copy the implementation from existing Reth. Instead of calling state_at_block_id, we can call our own function which will handle falling back to latest state if that was requested.

• Latest: return latest state provider
• Historical >= earliest block number: return external state provider
• Historical < earliest block number: return existing historical state provider (slow and limited, so expected to return an error here)
