feat: Add production schema deployment scripts

- Create apply-schema-prod.js for deploying schema to any SurrealDB instance
- Create deploy-schema.sh to easily deploy using .prod.env
- Add npm scripts: schema:apply (local) and schema:deploy (production)

Usage:
  pnpm schema:deploy  # Deploy to production using .prod.env
