Sprint 6: Таймлайн X home variant for chronic patients

Fourth home variant alongside Карточки / Лента / Таймлайн,
labeled "Таймлайн X" in Tweaks "Главный экран". Designed for
patients with chronic conditions (not post-op).

data.js: new `chronic` object — condition, stage, doctor,
metrics (days since last flare-up, compliance %, flare-ups this
year), daily + scheduled tasks, lifestyle recommendations, and
5-visit observation history.

HomeTimelineXScreen sections:
- Health status hero with soft gradient primary-100 → warm-100,
  success-tinted stable-state chip (green dot), three narrow-font
  metrics
- Today's tasks card: daily habits with streak + 🔥, scheduled
  procedures with dates
- Ask-a-question promotion: AI card (teal gradient) + doctor
  card (with avatar) side by side
- Vertical observation timeline: 5 past visits with doctor initial,
  color-coded by type (diagnosis/procedure/therapy/flareup/checkup)
- Upcoming appointment, lifestyle recommendations carousel with
  emoji, book CTA, article carousel

Softened hero from dark teal gradient with white text to light
primary-100 → warm-100 gradient with dark text — stable-state
signal, not clinical verdict.

Following Sprint 5 convention: matching entry in src/docs.js under
key `home:timelineX` with title, category, goal, tasks, rationale.
