feat: Implement frontend asset build process and update Docker configuration

- Added a new build script using esbuild to bundle JavaScript and CSS assets, including Tailwind CSS and Font Awesome.
- Updated the Dockerfile to include a multi-stage build process for frontend assets, ensuring efficient image creation.
- Enhanced GitHub workflows to automate the installation of Node.js dependencies and build frontend assets during CI/CD.
- Introduced a .gitignore entry for the dist directory to prevent unnecessary files from being tracked.
- Improved caching and content type handling for static files served by the application.
