Sortable Options for Live Chat

We've enhanced the Live Chat feature by adding multiple sorting options. Now, agents can sort conversations by:

- Last message (ascending/descending)
- Created at (ascending/descending)
- Last interaction (ascending/descending)
- Subscribed at (ascending/descending)

This update allows for more efficient handling and prioritization of live chats based on the agent's needs.
