chore: sort completed transactions

[mmrrnn]

Description

This pull request focuses on refactoring the transaction handling in the wallet service by replacing HashMap with Vec for storing transactions. This change impacts several parts of the codebase, including transaction service responses, database storage, and transaction handling logic. Additionaly, we sort txs by mined_timestamp in desc order.

Testing

Tested manually using minotari_console_wallet

I would not do an order here in rust.
I would change it where it gets it from the database and use SQL to to do the order.

Also don't order by timestamp, order by mined_timestamp
