fix(credentials): translate auth errors and require OneCLI for spawn

Two related fixes for the case where credentials aren't usable:

1. Replace Claude Code's "Not logged in / Invalid API key · Please run
   /login" output with a host-aware message. The user can't run /login
   from chat, so the raw text is unhelpful. Provider gains an optional
   isAuthRequired() classifier; the poll-loop substitutes the message
   on both result-text and error paths.

2. Treat OneCLI gateway failure as a transient hard error instead of
   spawning a credential-less container. The catch in container-runner
   now propagates; router and host-sweep wrap wakeContainer to log and
   leave the inbound row pending so the next 60s sweep tick retries.
   Router also stops the typing indicator on failure.
