Update filter type and refactor DocSearchView component

- Made the `label` property in the `Filter` type optional for greater flexibility.
- Added `TextField` import in `doc-search-view.tsx` for user input.
- Removed `DocSearch` and `DocSort` components, replacing them with a `TextField` that uses `filter.label` or `filter.type` as its label.
