The admin AI assistant is now easier to keep alongside your work:
- When the assistant chat is open, it stays open as you move between admin pages and greets you on each new page, so you can ask about whatever you are viewing.
- Switching tabs or filters on the same page keeps the assistant in place without repeating its greeting.
- Fixed a display issue where the collapsed "messages from other pages hidden" summary could stretch the chat sideways; it now shows a simple count and stays within the chat width.
