feat: docsgpt up runs and manages DocsGPT on Docker

`docsgpt up` copies the standalone Compose file shipped with this package
version into the stack directory (~/.docsgpt/server by default), writes its
.env and starts the stack on the images of the same version. A first run
asks who should reach DocsGPT (this computer, the network with a token, or a
domain with HTTPS) and which model provider to use; flags answer the same
questions for scripts. Re-running keeps secrets and settings and moves the
image tag, and the database password is only generated for a new database.

Also: down, status, logs, token, open, env, upgrade (uv tool installs
upgrade themselves and run `up` again) and uninstall (keeps settings and
data unless --purge). The commands import no Flask, Celery or settings.

The wheel carries deployment/docker-compose-standalone.yaml as
docsgpt/deploy/docker-compose.yaml; the sdist includes the source file.
