Subject: [PATCH] Create Dockerfile

This Dockerfile sets up a multi-stage build for a web application:

    The first stage compiles the Golang backend code and creates a 'main' binary.
    The second stage handles frontend asset compilation, specifically converting SCSS to CSS using SASS.
    Finally, it combines the Golang binary and compiled CSS into a final image, ready to run the web application on port 8080.
