feat(apple): contacts screen and consent prompts

Device list, detail, and block list under Settings, plus the two sheets:
an incoming offer and a device asking to be remembered. Both are
answer-only, since swiping away would leave the sender waiting.

Accepting an offer routes the released ticket into the ordinary receive
path, so the platform still chooses the destination. The prompt does not
ask a second time; it only falls back to the review sheet when the
destination is unusable.
