Refactor ExtractorPage with custom hooks and UI components

* Extract logic and state management from `ExtractorPage.tsx` into a custom hook `useExtractor.ts`.
* Extract log rendering logic and auto-scrolling into a separate `LogPanel.tsx` component.
* `ExtractorPage.tsx` is now significantly smaller, focused purely on presentation.
* Verified no regressions via type checking and application building.
