feat: add initial Dockerfile, SSH server apps, and media upload web component

Add DockerfileDrive for containerized deployment with Python 3.12.8 Alpine base, including SSH host key and pip setup. Implement multiple SSH server variants: app.py with SFTP file transfer support on port 2225, app2.py with custom bash shell spawning, app3.py with terminal resize handling, app4.py with bcrypt password authentication, and app5.py with chat client infrastructure. Include TileGridElement and UploadButton custom web components in media-upload.js for gallery-style image display with hover effects.
