Pull request overview

This PR extends the shared PostgreSQL Swarm stack to support the Fashion crawler in production by attaching the production-only Fashion overlay network alias and ensuring the Fashion database/role are provisioned during production deploys, with docs and static validation updated to match.

Changes:

• Add a production-only makepad-postgres-fashion service alias backed by a new external overlay network variable (MAKEPAD_POSTGRES_FASHION_DB_NETWORK).
• Provision the Fashion database/role during production deploys and introduce an idempotent bootstrap SQL script (bootstrap/fashion-app.sql).
• Update README documentation and the static validation script to enforce the new wiring and bootstrap expectations.
