…ing (#29914)

## **Description**

This PR adds minimal Predict confirmation hook plumbing needed by the
upcoming Polymarket Deposit Wallet migration.

It wires TransactionController confirmation lifecycle hooks to
PredictController while keeping Predict behavior as passthrough by
default:

- `beforePublish` delegates to `PredictController.beforePublish`, which
currently returns `true`.
- `publish` delegates to `PredictController.publish` before Transaction
Pay / 7702 / Smart Transactions, and continues normal publishing when
Predict returns no transaction hash.
- If a future Predict publish implementation returns `{ transactionHash,
isIntentComplete: true }`, TransactionController marks the latest
transaction meta as `isIntentComplete` before returning the hash.

This PR intentionally contains no Polymarket Deposit Wallet business
logic. It is a small foundation PR for confirmation-team review.

## **Manual testing steps**

```gherkin
Feature: Predict confirmation hook plumbing

  Scenario: non-Predict transactions continue through the normal publish flow
    Given a transaction is published through TransactionController
    And PredictController.publish returns no transaction hash

    When the publish hook runs
    Then Transaction Pay / 7702 / Smart Transaction publishing continues as before

  Scenario: Predict publish can complete a transaction intent
    Given PredictController.publish returns a transaction hash and isIntentComplete

    When the publish hook runs
    Then normal publishing is short-circuited
    And the latest TransactionController transaction meta is marked intent complete
```

Local validation run:

```bash
yarn jest app/core/Engine/controllers/transaction-controller/transaction-controller-init.test.ts app/components/UI/Predict/controllers/PredictController.test.ts --runInBand
yarn lint:tsc
```

exercised.
- [x] I've tested with a power user scenario
  - N/A — hook plumbing only, no account/token rendering path changed.
- [x] I've instrumented key operations with Sentry traces for production
performance metrics
  - N/A — this PR only adds passthrough hook plumbing.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Touches transaction publishing lifecycle by adding new hooks and a
short-circuit path, which could affect submission ordering and
integration with Pay/7702/Smart Transactions if miswired. Default
behavior remains passthrough, reducing blast radius.
> 
> **Overview**
> Adds Predict-specific confirmation hook plumbing into the transaction
submission lifecycle. TransactionController init now calls
`PredictController:beforePublish` as a new `hooks.beforePublish`, and
calls `PredictController:publish` at the start of `hooks.publish`,
**short-circuiting** the rest of the publish pipeline when Predict
returns a `transactionHash`.
> 
> Updates PredictController to expose new messenger methods
(`beforePublish`, `publish`) with default passthrough implementations,
extends messenger action typings/permissions accordingly, and adds unit
tests verifying delegation, call ordering, and the short-circuit
behavior.
