Rework client UI state: move and update showLogin/showApp in public/app.js to explicitly set display styles when toggling screens and ensure user info and file load on app show. Remove the theme toggle from public/index.html and simplify CSS by collapsing color variable definitions (dark-theme-focused) in public/style.css. Add a VS Code workspace file. Remove the old uploads/Think app (Dockerfile, package.json, server.js and associated lockfile).
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.
