fix(deploy): always copy docker-compose.yml to server

The 'Start Docker stack' step used '[ -f ... ] || cp' for
docker-compose.yml, which only copied the file on the first
deploy. Subsequent deploys kept the stale copy on the server.

The stale copy still had the dead 'nextjs' service with
'env_file: ../.env.production', which docker compose validates
on every 'up' and bailed because .env.production is written
later by the 'Deploy' step.

Changed to unconditional 'cp -f' so the server always has the
latest compose file.
