[CONTRACT] No on-chain event emission - AutopilotVault is not auditable on Stellar Explorer

[thisisouvik]

Description

The AutopilotVault Soroban contract in contracts/src/lib.rs has no event emission (env.events().publish()) for any action. This makes it impossible to:

• Audit contract interactions without querying Horizon API separately.
• Build indexers or subgraphs on top of the contract.
• Detect re-entrancy or double-spend scenarios at the contract layer.

Expected Behavior

Every state-changing function (initialize, withdraw) should emit a Soroban event.

Suggested Fix

// In withdraw():
env.events().publish(
    (symbol_short!(withdraw), owner.clone()),
    (token_address.clone(), amount),
);

Impact

High - Without events, on-chain auditability is zero. Stellar Expert cannot surface contract activity.
