Initial commit: simple file server

Add a new simple-file-server project. Includes Express server, auth and file routes, static client assets (public), and a db/connection module that uses MariaDB to log file actions and initialize a users table. Add Dockerfile and docker-compose.yml (exposes 3000 → 8080 and mounts ./uploads), .env.example, .gitignore, package.json and package-lock.json, and an uploads scaffold. This provides a ready-to-run app with container support and basic DB integration.
