feat(templates): support isolated = false opt-out in template.toml

Templates using network_mode: host (e.g. cloudflared) can now declare
isolated = false in their [config] section to prevent Dokploy from
injecting networks into the compose, which would cause a Docker error.

Default behavior (isolated = true) is unchanged for all existing templates.

Fixes #4366
