- Add function to retrieve all transactions for a given user - Orders results by id DESC (newest first) - Returns TransactionRow[] with full transaction details
- Implement JWT-protected endpoint to fetch user transaction history - Validate user_id and verify JWT authorization (403 on mismatch) - Enrich transactions with Horizon data (timestamp, amount, destination) - Use Promise.all for parallel Horizon API calls - Handle edge cases: empty transactions, invalid user_id, Horizon errors - Return 200 with enriched transaction list or empty array
- Add 10 test cases covering success and error scenarios - Mock Horizon API calls (transactions and operations endpoints) - Test validation: invalid/negative/zero user_id - Test authorization: JWT mismatch (403), invalid JWT (401) - Test error handling: Horizon failures (500) - Test edge cases: empty transactions, no payment operations - Achieve 100% coverage for new endpoint

🛠️ Issue
Closes #139
📖 Description
This PR implements a new endpoint to retrieve transaction history for Stellar wallets on Testnet. The endpoint fetches transactions from the local SQLite database and enriches them with detailed information from the Horizon API, including timestamps, amounts, and destination addresses.
