chore(release): v1.6.0

Medication editor overhaul, route of administration, today-tile read-flip.

- Route-of-administration column (ORAL | INJECTION | OTHER) decoupled from
  treatmentClass; injection-site picker surfaces for any injection.
  Migration 0088 backfills ORAL via a constant column default.
- One-time injection (oneShot + deliveryForm = INJECTION) editor path.
- Profile-photo upload card on Settings → Account.
- Today-tile read-flip: /api/medications/intake?scope=today and
  /api/dashboard/summary gate through the canonical recurrence engine,
  matching the reminder worker for bi-weekly, rolling, RRULE, and one-time
  cadences.
- Measurement note cap 25 → 200; dashboard range colors on semantic tokens;
  admin sidebar icons + shared-helper consolidation; API-tokens multi-language
  snippets restored.
