feat(blueprint): add engram template

Engram Cloud is a self-hosted persistent-memory sync server for AI
coding agents. Deploys the published ghcr.io/gentleman-programming/engram
image with a PostgreSQL backend, auto-generated auth secrets (cloud
token, admin token, JWT secret), and a domain on the dashboard/API port.
