"""The advisor chat UI bundle (goal 27, task 2): the /chats list, the
/chats/{id} session page, the dashboard hero composer and the statum
actions under them, driven end-to-end against the scripted LLM
endpoint (the same ScriptedLlm the backend bundle uses). The scenes:

- the pages render: /chats lists the user's chats (title, status
  chip, delete action), the dashboard carries the hero composer
- the hero: StartAdvisorChatAction creates the chat titled from the
  first line (clamped), records the message, kicks the turn and
  navigates to /chats/{id}
- a chat page: the transcript slot carries the user message, the
  scripted tool call round (name/arguments/result parsed from the
  payload), the parked question with its options, and the send
  action is sealed against the chat
- answering: the question card's answer rides SendAdvisorMessage's
  answer path -> "Human selected: ..." lands, the turn resumes and
  the final assistant reply appears in the slot
- the refresh action: RefreshAdvisorChatAction rebuilds the slot
- suggestions: the card state (title/mandate/mode/priority + the
  sealed decide action) renders from the inserted row
- delete: the chat leaves the list and its page state reads as
  not-found (id 0)
- privacy: a second user's /chats slot sees none of the first
  user's chats and their /chats/{id} slot renders not-found
- the unconfigured dashboard: the hero renders with
  advisor_configured false
