Add the Tailscale CLI to the production image and document how to
enable Let's Encrypt cert provisioning for virtual printers from a
Docker-deployed Bambuddy.
- Dockerfile installs `tailscale` from the official Debian repo. Only
the CLI is used at runtime; tailscaled itself stays on the host.
The binary is harmless if the socket isn't mounted — the code logs
an actionable hint and falls back to self-signed certs.
- docker-compose.yml adds a commented-out volume mount for
/var/run/tailscale/tailscaled.sock with inline setup instructions.
- tailscale.py's docker-socket hint now also fires when the binary is
present but the daemon socket is unreachable (i.e. the new Docker
pattern), not just when the binary is missing, so users get the
actionable "mount the socket" message instead of opaque CLI stderr.
Enabling the integration on a Docker host:
1. `curl -fsSL https://tailscale.com/install.sh | sh` on host
2. `sudo tailscale up`
3. `sudo tailscale set --operator=<user>` for the container PUID
4. Uncomment the tailscaled.sock mount in docker-compose.yml
5. `docker compose up -d --force-recreate`
6. Flip the Tailscale toggle on the VP card
