Bug: APY calculation incorrect after transactions

[starksama]

Description

APY/APR calculation is wrong after transactions (deposit, withdraw, rebalance).

Root Cause

The tx history is not correctly including the transaction just submitted, causing stale/incorrect APY values to be displayed.

Expected Behavior

After a tx completes, the APY should immediately reflect the new state.

Steps to Reproduce

1. Make a deposit/withdraw/rebalance transaction
2. Observe the APY display immediately after
3. APY shows incorrect/stale value

Priority: High
