Add integration test: deposit → rebalance → yield → withdraw full cycle

[devsimze]

Problem

End-to-end on-chain flow is split across files; one canonical scenario helps regressions.

Scope

• New test or extend test_rebalance_integration.rs

Acceptance criteria

• Single test covers full lifecycle with assertions on shares, assets, and events.

Hi,I'd like to work on this issue. I'll add a comprehensive integration test covering the complete lifecycle—deposit → rebalance → yield accrual → withdraw—either as a new test or by extending test_rebalance_integration.rs, with assertions validating share accounting, asset balances, and emitted events throughout the flow.
