Add "Rank" and "Transactions count" columns to section /accounts

[Viterbo]

Overview

Two columns are currently empty due to a lack of data:

• Rank: This number can be easily calculated based on the pagination parameters (no need for indexer changes).
• trxCount: This field can be set to a loading state while we fetch the corresponding data from the indexer.

Fixed here: #953

The reason for separating the trxCount data from the initial query is to allow the first query to complete quickly, enabling the user to see some final data right away, even if not all information is available yet.

This issue includes (or replaces) this other issue requesting only the count column: #934
