Auto-create Paperclip instance config.json on first boot

bootstrap-ceo exits early with "No config found" when config.json is absent.
Generate a minimal valid config at PAPERCLIP_CONFIG before launching Paperclip,
using env vars for DB URL, public URL, and deployment mode. Skipped when config
was already restored from HF Dataset backup.
