Tighten callback flow: no booking questions, no re-asking

On a real order-status call the callback note saved correctly, but AVA leaked
booking behavior: it asked for insurance, asked the caller "what's the status of
your order" (which is what THEY were asking), and re-asked the name. Rewrote the
callback branch as explicit short steps: acknowledge it can't look it up; note
what they're asking (don't make them repeat it, never ask the caller for what
only staff can look up); get the name only if not already given; confirm the
callback number; promise a staff callback. Explicitly: no insurance/office/
day-time for callbacks. Verified clean on the order-status scenario.
