feat: human error states, operator toasts and a queue/origin view in the omp UI

- classify transport and API failures into a short state with the next step
- count undelivered messages and show them next to the sent counter
- toast on owner paired, connection recovered and reply not delivered (throttled)
- second status line previews the next queued turns
- host spinner names the Telegram prompt while its turn runs
- sanitize every Telegram-controlled string that reaches the widget
