Add infrastructure: Terraform, Docker Compose, BRouter, CD pipeline (#2)

Terraform:
- Hetzner CX22 server with Docker, firewall (80/443/22)
- SSH key and output for server IP

Docker Compose:
- Caddy reverse proxy (auto HTTPS)
- Journal and Planner app containers
- BRouter routing engine container
- PostgreSQL + PostGIS
- Garage S3 storage

BRouter:
- Dockerfile based on eclipse-temurin:11-jre
- Segment download script for Germany (4 tiles, ~750MB)

CD Pipeline:
- Build & push Docker images to ghcr.io on main push
- Deploy step commented out (enable when server provisioned)

Scripts:
- PostgreSQL daily backup with 14-day retention
- Dockerfiles for both apps (multi-stage builds)
