Add subscription: true to integration, external API, and email nodes

Nodes requiring integrations (Discord, Google Mail, Google Calendar, LinkedIn,
GitHub), external LLM APIs (Anthropic, OpenAI, Gemini, Replicate), external
agent providers, and email nodes now require a subscription. Cloudflare-internal
nodes (Workers AI, Browser Rendering, Containers) are unchanged.
