feat: add support for predict deposit and order

[caieu]

Explanation

Summary

This PR adds support for a new predictDepositAndOrder transaction type in the transaction-controller. It updates the TransactionType enum, associated types, tests, and changelog to recognize and support this combined operation.

Why

To enable clients (e.g., Predict integrations) to handle transactions that combine deposit + order placement into a single transaction type, improving consistency and simplifying transaction handling across consumers.

Changes

• ➕ Added TransactionType.predictDepositAndOrder to the TransactionType enum.
• 🛠 Updated related TypeScript types to support the new transaction type.
• 🧪 Added test coverage to validate the new enum value is defined and exported correctly.
• 📝 Updated CHANGELOG.md.

Test Plan

• Confirmed the new transaction type is properly exported.
• Ensured existing tests pass with the new enum value included.

Note

Low Risk
Low risk additive change limited to TypeScript enum and changelog; main risk is downstream consumers needing to handle the new transaction type value.
