Never claim the appointment is confirmed; clean phone-confirm + insurance

Fixes from a test call:
- Contradiction: AVA said "staff will confirm" then later "we've got your
  appointment scheduled". Hardened the rule — never say booked/scheduled/set/
  confirmed (even in the recap); it's always a REQUEST staff confirm on callback.
  Wrap-up recaps as "I've noted your request...".
- Phone: it asked "may I read your number back?" then read it anyway. Now states
  it directly in one line ("I have your number as <number> - is that best?"),
  no permission ask, don't skip.
- Insurance: stop saying "we accept/take <plan>" (it said "we accept All State",
  which isn't even a listed plan) — just note it, staff verify.
