feat: app-host → телефон-эмулятор (Jellyfin + mirror + стейт + команды)

- Config.kt: env > application.properties > дефолты (креды не в коде)
- PhoneState.kt: единый стейт — mode, currentItem, audioIndex, mirrorStatus, activeSessionId, сессии (эмуляция), downloaded
- PhoneActions.kt: catalog (с бейджами зеркал), open, watch (PlayVideo на очки), makeMirror, mirrorStatus, download/delete, sessions/selectSession, status
- Main.kt: новые консольные команды (catalog/open/watch/mirror/dl/rm/sessions/session/status)
- GlassesHub: Welcome берёт mode/sessionId из стейта, glasses_off → пауза
- JellyfinClient.item() — элемент по id (для open/watch)
- 58 тестов, 130 всего, все зелёные; живые проверки: catalog (реальный Jellyfin), watch (PlayVideo с s3-url), status (стейт обновляется)
