🍕 Feature

Current behavior

The app currently returns all the user's transaction. In the long run, showing everything can become expensive both for the backend and database processing and for the user's machine.

Suggested solution

• By default, show only the current day's transactions;
• Add query parameters start_date and end_date to the endpoint GET: /user/me/transactions;
• Use the provided query parameters to filter by date.
