Added Docker Compose and Makefile

[fezfez]

This PR introduces Docker Compose and a Makefile to standardize and simplify the development environment setup and management.

Advantages

• Standardized Environment: Ensures that all developers are using the same environment, reducing "it works on my machine" issues.
• Simplified Setup: Developers can now use make install and make dev commands to set up and start the development environment quickly.
• Easy Management: Docker Compose handles dependencies and services, making it easier to manage and run the application.
• Port Configuration: Added ability to configure the host and port via environment variables, improving flexibility.

Changes

• Added .env.example with example environment variable for the host.
• Added docker-compose.yml to define services and dependencies.
• Added Makefile with targets for common tasks (install, dev, dup, kill).
• Updated README.md with instructions for using Docker Compose and Makefile.
• Modified nuxt.config.js to support environment variable configuration for the host.
