Subject: [PATCH 1/2] feat(dashboard): demo console with web chat, demo clock,
 scenario playback and split screen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- pages/2_Демо-консоль.py: persona selector, virtual clock bar (+1 h, to 08:00/20:00,
  next day, reset with confirm), fallback patient web chat (buttons from Reply.buttons,
  kind styling, outbox drained after every action and on a 2 s fragment poll), scenario panel
- pages/3_Сплит-экран.py: patient chat or PATIENT_WEB_URL iframe on the left, compact doctor
  panel (patients, live alerts, red banner on a new acute alert) on the right
- console/playback.py: data/synthetic/<persona>.jsonl runner (advance_to/press/text/
  expect_color/start), date chaining between days, pause on failure with retry/skip/manual
- console/api.py: own HTTP client over the frozen API contract, ApiError only

Subject: [PATCH 2/2] feat(dashboard): console fallbacks for the real API (#12)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 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

Refs #17
