fix: rewrite headless results logic in hook, making sure all pages will be...

This merge request:

• Moves the headless results logic from component to hook
• Completely rewrites the headless results loadAllPages logic, so it works without setting a manual delay and uses a reusable loadNextPage function
• Adds logic so each time the search query or filters update, all pages will be reloaded with the updated state
• Adds type to all type imports where this was not already the case
