feat(ai): open Ask AI side panel with a preprompt in two modes (#22582)

Add the ability to open the Ask AI side panel pre-filled with a prompt
from any frontend component, with a mode to control whether the message
is sent automatically or left for the user to review.

- agentChatPrepromptState: holds the pending preprompt and its mode
(PREFILL = fill only, SEND = fill and auto-submit)
- useOpenAskAiPageWithPreprompt: seeds the new-thread draft, opens a
fresh Ask AI thread and stores the preprompt intent
- AgentChatPrepromptEffect: applies the intent once the chat editor and
send listener are mounted, either restoring the editor content or
dispatching the send event and clearing the editor
