The DestinationPicker now offers every type that exists (user, voicemail,
ring group, digital receptionist, office hours, announcement, outside
number, hang up) on every page that routes calls; queues and
conferences join in M8. API summaries show the number of dialable
targets ("Ring group Sales (500)", 05 §3). Wizard step 8 gains "Ring
everyone": it creates or refreshes a ring group "Everyone" of all
extensions (unanswered → the first user's voicemail); an IVR isn't
created there because it needs a recorded greeting. m3-t5 now routes
the main number through "Ring everyone" and still passes.
