Implement lender investment tracking in contract

🔍 Description

Implement functionality in the smart contract to track lender investments, including amounts, timestamps, returns, and investment status.

💡 Proposed Solution

• Add data structures to track investments per lender
• Implement functions to query investment history
• Track returns and accumulated earnings
• Events to notify investment changes
• Query functions for frontend dashboard

🧠 Motivation / Related Problem

To be able to display real data in the lenders dashboard (UI), we need the contract to provide investment information in a structured and queryable way.

• getLenderRewards(address lender) - Returns accumulated rewards
• getLenderInvestmentHistory(address lender) - Returns history
• Events: InvestmentMade, RewardsDistributed, WithdrawalMade

Hey @JosueBrenes ,
I’m a Soroban dev and excited to implement lender investment tracking! Right now, the contract lacks structured data for the dashboard—no way to query investments, returns, or history.

My plan:
1.Data structures to track per-lender:

• Investment amounts/timestamps/status.
• Accumulated returns & rewards.

2. Core functions (gas-optimized):

• getLenderInvestments() / getLenderTotalBalance().
• getLenderRewards() / getLenderInvestmentHistory() (with pagination).

3. Events for real-time updates:

• InvestmentMade, RewardsDistributed, WithdrawalMade.

looks good? Assign
