🐛 fix(ratio-sync): reset pagination when filter/search changes

Add a `useEffect` hook in `UpstreamRatioSync.js` to automatically set
`currentPage` to `1` whenever `ratioTypeFilter` or `searchKeyword`
updates.
This prevents the table from appearing empty when users switch to the
“model_price” (fixed price) filter or perform a new search while on a
later page.

Additional changes:
- Import `useEffect` from React.

This enhancement delivers a smoother UX by ensuring the first page of
results is always shown after any filtering action.
