Describe the feature

When handling chain notifications (committed, reorged and reverted), extract addresses changed in the execution outcome.

    let addresses: Vec<Address> = chain
        .execution_outcome()
        .accounts_iter()
        .map(|(address, _)| address)
        .collect();
    
    self.update_address_mapping(&addresses).await?;

Add helper methods:

• update_address_mapping() - Write new addresses to HashedAddressMapping (idempotent)
