🔖 Title

E2E Tests for Liquidity Operations Flow

---

📄 Description

Create end-to-end integration tests for liquidity provider operations including deposits, withdrawals, and portfolio tracking. Mock blockchain pool contract interactions. This issue can be completed independently once issues #51, #52, #53, #54, #62, and #63 are implemented.

Related to: Meta-issue #68

✅ Tasks to complete

• Test public pool overview endpoint (GET /liquidity/overview)
• Test deposit endpoint (POST /liquidity/deposit)
• Test transaction submission for deposit (POST /transactions/submit)
• Test investment summary endpoint (GET /liquidity/my-summary)
• Test withdrawal endpoint (POST /liquidity/withdraw)
• Test transaction submission for withdrawal
• Test complete flow: deposit → submit → confirm → check summary → withdraw
• Test validation errors (minimum deposit, insufficient shares)
• Verify database state changes (deposit history, share balances)
• Mock Soroban pool contract interactions
• Test APY and earnings calculations
• Clean up test data after tests
