Pre-merge author checklist

[ ] I've followed MetaMask Contributor Docs and MetaMask Extension Coding Standards.
[ ] I've completed the PR template to the best of my ability
[ ] I’ve included tests if applicable
[ ] I’ve documented my code using JSDoc format if applicable
[ ] I’ve applied the right labels on the PR (see labeling guidelines). Not required for external contributors.

Pre-merge reviewer checklist

[ ] I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
[ ] I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

[!NOTE] Removes the redesigned_confirmation UI customization from metrics, deletes related detection logic, and updates tests and helpers accordingly.

Metrics/Tracking:

Remove redesigned_confirmation from ui_customizations in transaction and signature tracking (app/scripts/lib/transaction/metrics.ts, app/scripts/lib/createRPCMethodTrackingMiddleware.js).

Delete redesign-dependent logic (shouldUseRedesignForTransactions/signatures) and associated approval-type mapping.

Ensure ui_customizations is null when empty; only include SIWE/Permit/Order/GasEstimationFailed/Blockaid flags.

Always read transaction_advanced_view without redesign gating.

Constants:

Remove MetaMetricsEventUiCustomization.RedesignedConfirmation from shared/constants/metametrics.ts.

Tests:

Update unit and e2e tests to drop redesigned_confirmation expectations and assert ui_customizations: null or only relevant values (e.g., sign_in_with_ethereum, permit, order, flagged_as_malicious).

Adjust signature helpers to only include ui_customizations when non-empty.

UI:

Remove redesign customization from ERC20-decimals tracking hook (useTrackERC20WithoutDecimalInformation).
