Consistent transactions sort

[Alenar]

Content

This PR changes the order of retrieval of the Cardano transactions from the database.

Before we used SQLite rowid but this order isn't guaranteed to be consistent across node since it depends on the order of insertion in the database. To solve this issue this PR change the order to the use the transaction block_number then its transaction_hash.

An composite index on those columns is added to ensure a fast retrieval, plus a benchmark is added to measure the retrieval performances.
