Add self-hosted Docker deployment guide to README

[t0mdavid-m]

Summary

Added comprehensive documentation for deploying OpenDIAKiosk using Docker on self-hosted infrastructure, including step-by-step instructions for pulling images, running containers, and managing persistent data.

Key Changes

• Docker deployment section — New "Self-hosted deployment" section with instructions for pulling prebuilt images from GitHub Container Registry
• Container setup guide — Detailed docker run command with explanations of key flags:
  • Port mapping for Streamlit UI access
  • Optional read-only bind-mount for MS data files with auto-detection
  • Persistent workspace volume for preserving user data across restarts
• Remote access instructions — SSH tunnel setup for secure access when the host lacks a public IP or has firewalled ports
• Update procedure — Clear steps for upgrading to new versions while preserving user workspaces
• Kubernetes reference — Note directing users to separate Kubernetes deployment documentation for production cluster setups

Notable Details

• Emphasizes that the workspace volume persists across container removals, enabling seamless upgrades
• Explains the read-only mount strategy for data files to avoid unnecessary copying
• Provides both interactive shell and non-interactive SSH tunnel options for different use cases
