Further comments

This pull request refactors the Omnichannel unit autocomplete functionality in the Rocket.Chat repository. The changes introduce a new React hook, useUnitsList, which leverages @tanstack/react-query to fetch and manage a paginated list of Omnichannel Business Units. This hook supports text filtering, an optional 'None' item, and custom limits per page.

The AutoCompleteUnit component has been refactored to simplify its implementation by directly using the useUnitsList hook. This change enhances type safety and integration with PaginatedSelectFiltered by updating the component's props definition with ComponentProps and Omit. Additionally, the effect for loading items and pagination logic has been streamlined.

Similarly, the AutoCompleteUnits component has been refactored to simplify its props definition using Omit and streamline data fetching by utilizing the useUnitsList hook. This refactoring removes previous dependencies and complex state management, improving the component's maintainability.
