test: Re-enable Staking smoke test (MetaMask#16682)

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

## **Description**
This PR re-enables the staking smoke test and removes the dependency on
the Hoodi network, since staking can also work locally on Anvil, as
shown in the video below. Using Hoodi was no longer possible because
external calls are no longer allowed in the mobile test framework

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Re-enables and modernizes staking E2E coverage and aligns UI
selectors/actions with the new confirm flow.
> 
> - Rewrite `stake-action-smoke.spec.ts` to use `withFixtures` with a
forked Anvil local node (mainnet fork), perform staking of `1 ETH`,
verify activity, and assert wallet state; removes legacy
import/send/unstake/claim flows and unskips the test
> - Update E2E selectors and page object: `UNSTAKE_CONTAINER` now uses
`earn.withdraw`; replace `CONTINUE` with `CONFIRM`, and rename
interactions from continue→confirm
> - CI: enable pooled staking in E2E builds by setting
`MM_POOLED_STAKING_ENABLED='true'` in Android and iOS workflows
>
