feat(dashboard): console fallbacks for the real API (#12)

- personas degrade: /demo/personas → doctor's patients (hero first) → env token
- scenario file guessed from the transliterated first name (andrey.jsonl), like the backend
- «Подключить демо-пациента»: connects the synthetic hero via /patients/connect when no seed
- connect code prefilled from ?code= of the console link
