FN-6633: guide chat agents to ask questions for options

Encourage dashboard chat agents to turn option sets into selectable ask-question cards.

- Expand chat-lane prompt guidance so options, choices, and alternatives use `fn_ask_question` instead of prose-only lists.
- Cover the guidance in chat manager tests and assert the prompt is passed to resolved sessions.
- Record the patch changeset and quarantine unrelated flaky dashboard tests observed during verification.
