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

Refactors latency metrics to use refs and UI-init timing, conditionally updates/returns values, and updates usage/tests accordingly.

Hooks:
- ui/pages/confirmations/hooks/transactions/dapp-swap-comparison/useDappSwapComparisonLatencyMetrics.ts
  - Replace state/context timing with useRef-based timers anchored to UI init time.
  - Make updateSwapComparisonLatency() return the latency string; expose stringified latencies.
Usage:
- useDappSwapComparisonInfo.ts
  - Call updateRequestDetectionLatency() only when quotesInput is present.
  - Use returned swapComparisonLatency from updateSwapComparisonLatency() for metrics.
  - Improve error reporting by sending actual error string; adjust dependencies accordingly.
Tests:
- useDappSwapComparisonInfo.test.ts
  - Update mocks to reflect new latency API (mock updateSwapComparisonLatency return value) and expectations.
