feat: add Paperclip env example file with placeholder secrets

Add env/.env.example.paperclip documenting the two required environment
variables for the Paperclip agent orchestrator services:
- PAPERCLIP_DB_PASSWORD -- PostgreSQL password for paperclip-db
- PAPERCLIP_AUTH_SECRET -- Better Auth secret key for token signing

Users copy this to .env and fill in the secrets before deploying.
