Fix/thread sorted and drag drop (#5046)

Modified the `onDragEnd` handler in `ThreadList.tsx` to use the complete global thread list from the `useThreads` store. This resolves a bug where dragging and dropping threads could lead to items disappearing from "Favorites" or "Recents" sections by ensuring the reordering logic operates on the full dataset.

Additionally, the default `order: 1` initialization for new threads in `useThreads.ts` and `services/threads.ts` has been commented out this make thread sorted by newest to oldest
