feat(web): questionnaires, diary and medication module in the patient app

- Focus screen renders versioned questionnaire items (iq: buttons): section chip, position
  (adaptive forms without "of N"), recall date, pause / help-now actions, optional skip,
  sleep-hours input, 0-10 scale anchors, RUS-AUDIT item 2 standard-drink table.
- Paused / held-for-review questionnaires get their own screen.
- Today: intake and diary tasks, review notice, therapy-day card on days 1/7/14.
- Drug card /meds/:ref from data/meds/meds_reference.json (draft built from the Minzdrav
  guidelines: depression 2024, PTSD 2023) — expected effect, course, side effects, red flags;
  no doses shown. "Report a side effect" always available (med:side_effects:<ref>).
- API: /instruments/catalog, /meds/reference; today gains questionnaire state, reference id,
  indication and therapy day; demo persona seeds the dashboard dose history.
- INTAKE_DEMO=1 (demo clock only) opens the questionnaires on synthetic data without touching
  the clinical release gate in config/intake_runtime.yaml.
