refactor(predict): migrate usePredictOrderPreview to React Query (MetaMask#26875)

## Summary
- Migrate `usePredictOrderPreview` hook from manual state management to
React Query (`useQuery`)
- Extract query key factory and query options into
`queries/orderPreview.ts`
- Simplify debounced order preview calculation by leveraging React Query
for caching and automatic refetch

## Test plan
- [x] Unit tests updated and passing
- [ ] Verify order preview updates correctly when changing amount/side
- [ ] Verify debounce still works to avoid rapid recalculations

> [!NOTE]
> **Medium Risk**
> Behavior shifts from manual async/timer management to React Query
caching and polling, which can subtly change loading states, refresh
timing, and stale-data handling in UI consumers. Moderate risk due to
being user-facing trading/preview flows, though logic is mostly a
refactor with tests updated.
> 
> **Overview**
> Refactors `usePredictOrderPreview` from manual state/operation
tracking and custom timers to a debounced `useQuery` flow, using
`query.isFetching` for `isCalculating`, deriving `isLoading` from
`preview === null && !error`, and using `refetchInterval` for optional
auto-refresh.
> 
> Introduces `predictQueries.orderPreview` (new
`queries/orderPreview.ts`) with stable query keys, `keepPreviousData`
placeholder behavior, and an
`Engine.context.PredictController.previewOrder` query function; error
handling now parses localized messages and logs via `Logger.error` when
the query fails.
> 
> Updates the hook’s unit tests to run under a `QueryClientProvider`,
mock `Engine`/`Logger`, and align expectations with the new debounce,
loading, error, and auto-refresh behavior.
