Minor improvements to "Delete" functionality

To delete a chat, you need to first open it by clicking it, hit the Delete button, and then hit OK on the OK/Cancel message; this is cumbersome and platforms such as HuggingChat handle it much better

• Hovering over a chat brings up the Edit and Delete buttons; no need to first open or enter into the chat

• Hitting Delete brings up Yes and No in the same area, making the action much quicker

Option to “Bulk Delete” (such as offered by many email clients) has already been raised.
