chore: add Dockerfile, docker-compose, and .dockerignore for multi-service setup

Introduce a Dockerfile for building the Palmr application with multi-stage builds for both server and web components. Update docker-compose.yaml to consolidate services under a single 'palmr' service, ensuring proper health checks and environment variable configurations. Add a .dockerignore file to optimize Docker builds by excluding unnecessary files. Include a Makefile for simplified build and deployment commands.

.dockerignore
