test: fix unmatched mocked polymarket mocks (#30194)

<!--
Please submit this PR as a draft initially.

Do not mark it as "Ready for review" until this PR meets the canonical
Definition of Ready For Review in `docs/readme/ready-for-review.md`.

In short: the template must be materially complete (not just section
titles
present), all status checks must be currently passing, and the only
expected
follow-up commits must be reviewer-driven.
-->

## **Description**

> Prevents Polymarket E2E tests from leaking live requests by adding a
default gamma-api.polymarket.com/events/{id} mock response and ensuring
it matches any numeric event id.
> 
> Updates the trending feed mock for event details to use the same
generalized numeric-id matcher (instead of hard-coding /events/1), so
prefetch/highlight flows don’t crash on unmatched ids.

## **Changelog**

<!--
If this PR is not End-User-Facing and should not show up in the
CHANGELOG, you can choose to either:
1. Write `CHANGELOG entry: null`

(This helps the Release Engineer do their job more quickly and
accurately)

## **Pre-merge author checklist**

<!--
Every checklist item must be consciously assessed before marking this PR
as
"Ready for review". A checked box means you deliberately considered that
responsibility, not that you literally performed every action listed.

Unchecked boxes are ambiguous: they are not an implicit "N/A" and they
are not
a silent "skip". See `docs/readme/ready-for-review.md` for the full
checklist
semantics.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk: changes are limited to E2E test mocks/fixtures and
onboarding test flow, reducing flaky/unmocked network calls without
touching production logic.
> 
> **Overview**
> Prevents Polymarket E2E tests from leaking live requests by adding a
default `gamma-api.polymarket.com/events/{id}` mock and broadening
existing trending-feed event-detail mocks to match any numeric event id.
> 
> Updates onboarding E2E flows to proceed past the new
`OnboardingInterestQuestionnaire` step when opting into MetaMetrics,
adds a page-object wrapper for that screen, and seeds
`onboarding-fixture.json` with a stable `@MetaMask:AnalyticsId`.
