feat(perps): align PerpsController with core PR MetaMask#8633 (isInternal flag) (MetaMask#30413)

## **Description**

Mirrors the change from
[MetaMask/core#8633](MetaMask/core#8633) into
mobile ahead of the full migration to core, so the mobile copy of
`PerpsController` stays in sync with the upstream controller. The single
substantive change forwards `isInternal: true` in the `options` payload
when `PerpsController` submits a transaction via the
`TransactionController` messenger, matching the new core behavior that
flags controller-originated transactions as internal.

This keeps both codebases behaviorally identical until mobile retires
its local `PerpsController` in favor of the core package.

## **Changelog**

CHANGELOG entry: null

## **Manual testing steps**

```gherkin
Feature: Perps internal transaction flag parity

  Scenario: user submits a perps transaction routed through PerpsController
    Given the Perps feature is enabled and the wallet is unlocked

    When user initiates a perps action that triggers PerpsController to submit a transaction
    Then the resulting TransactionController entry is marked as an internal transaction (isInternal: true)
    And the transaction completes with the same UX as before this change
```

## **Screenshots/Recordings**

### **Before**

N/A — behavioral parity change, no user-visible UI difference.

### **After**

N/A — behavioral parity change, no user-visible UI difference.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Changes the options passed to `TransactionController:addTransaction`
for perps flows, which could affect how transactions are
classified/handled downstream (e.g., UI filtering or telemetry). Scope
is small and covered by updated unit tests.
> 
> **Overview**
> Perps transactions submitted via `PerpsController` now always forward
`isInternal: true` when calling `TransactionController:addTransaction`,
aligning mobile behavior with the upstream core controller.
> 
> Tests for `depositWithConfirmation` (including the `perpsDeposit` and
`perpsDepositAndOrder` paths) are updated to assert the new `isInternal`
flag in the messenger call options.
