feat(oauth)!: remove the didbot CLI and the confirm path master

`didbot-oauth` is the only agent-facing command now. The `didbot` binary, its `confirm` command, the `confirm` ask on the socket and the page-scraping Confirmer behind it are all gone; the loopback delivery the approve path needs already lives in its own module and stays. Nothing on the wire or the command line takes an account from its caller any more, so there is no identity left for a model to name wrongly.
