Make server deployable with Docker Compose on Coolify

- Read bind address and database URL from BIND_ADDR / DATABASE_URL (defaults unchanged for local cargo run) - Rename DockerFile to Dockerfile and rewrite it: current Rust for edition 2024, BuildKit cache mounts, non-root user, DB on /data - Add compose.yaml publishing ${HOST_PORT:-8080} with a persistent data volume, and a .dockerignore Co-Authored-By: Claude Opus 5.5 <[email protected]>
