Initial commit: Next Step health management app

A calm, reliable app to help manage appointments, medications, and notes
for chemo patients and their families.

Features:
- Today dashboard with next appointment and medications due
- Medication tracking with multiple schedule types (fixed times, interval, weekdays, PRN)
- One-tap dose logging with 5-minute undo window
- Questions for doctor tracking
- Family sharing with workspace model and invite links
- Offline-first with IndexedDB and sync
- Docker Compose deployment with Tailscale Funnel support

Tech stack:
- Next.js 14 (App Router) + TypeScript + Tailwind CSS
- PostgreSQL + Prisma
- Argon2 password hashing + session cookies
- Dexie.js for IndexedDB
