Update ledger size statistics to distinguish between UTXO & Account ledger sizes (Nova) [low]

[begonaalvarezd]

Description

Priority: low

It would be interesting giving the data of the "permanent storage" which is a combination between UTXO & Accounts ledgers (non prunable). I understand the IOTA Core team has to provide an INX endpoint so that the permanent storage size can be tracked. It would be good knowing what is the size of the UTXO ledger and then the rest so we can show statistics of both, distinguished, as the UTXO ledger size goes in pair with the locked in storage deposit, but the Accounts ledger not

Motivation

Improve ledger size statistics to accomodate to new IOTA 2.0 features
