Wire auth middleware into all products, add docker-compose and init-db script

- Auth middleware (JWT + API key + RBAC) copied into P3/P4/P5/P6
- All server entry points now register auth hooks + auth routes
- Webhook and Slack endpoints skip JWT auth (use HMAC/signature)
- docker-compose.yml: shared Postgres + Redis + Meilisearch, all 4 Node products as services
- init-db.sh: creates per-product databases and runs migrations
- P1 (Rust) and P2 (Go agent) run standalone, not in compose
