refactor(analytics): migrate Batch 3-15: mobile-platform (#26591)

## **Description**

Phase 3 analytics migration (Batch 3-15): migrate the ResetPassword view
from `MetaMetrics.getInstance()` / `MetricsEventBuilder` to the new
`analytics` utility and `AnalyticsEventBuilder`.

**Reason**: Deprecate MetaMetrics in favour of the shared analytics
utility and AnalyticsController.

**Changes**: `ResetPassword/index.js` now uses `analytics.trackEvent()`
and `AnalyticsEventBuilder` from `app/util/analytics`; test mocks
updated to mock the analytics utility instead of MetaMetrics.

## **Changelog**

CHANGELOG entry: null

## **Related issues**

Fixes: https://consensyssoftware.atlassian.net/browse/MCWP-302 (Batch
3-15)

## **Manual testing steps**

```gherkin
Feature: Settings analytics

  Scenario: user triggers a password change event
    Given app is open and user is in Settings > Change Password flow

    When user performs an action that triggers analytics (e.g. password change confirmation)
    Then the event is tracked on Mixpanel
```

## **Screenshots/Recordings**

N/A – analytics migration, no UI change.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk refactor limited to analytics plumbing in the password reset
flow; main risk is mis-tracking or missing the `PASSWORD_CHANGED` event
due to the API swap.
> 
> **Overview**
> Migrates `ResetPassword` analytics from legacy
`MetaMetrics.getInstance()`/`MetricsEventBuilder` to the shared
`analytics` utility with `AnalyticsEventBuilder`, keeping the
`PASSWORD_CHANGED` event and its biometry-related properties.
> 
> Updates the `ResetPassword` tests to mock `util/analytics/analytics`
instead of `MetaMetrics`.
