Fase 0: scaffold monorepo, SvelteKit skeleton, and dev infrastructure

- Turborepo + pnpm workspaces with apps/web and packages/types
- SvelteKit app: Tailwind, Paraglide i18n (en/es), keycloak-js, Supabase client,
  auth/collective stores, PWA service worker skeleton, all route placeholders
- packages/types: domain types (User, Collective, ShoppingList, etc.) and
  database.ts placeholder for generated types
- Justfile with dev, db-*, kc-*, build, backup, restore, deploy recipes
- infra/docker-compose.dev.yml: Postgres 15, GoTrue, PostgREST, Realtime v2.83,
  Storage, Kong (port 8001), Studio, Keycloak 24
- infra/docker-compose.prod.yml, kong.yml, db-init scripts, backup/deploy scripts
- keycloak/realm-export.json with colectivo realm and 5 dev test users
- supabase/config.toml and seed.sql with sample collective and items
- GitHub Actions: ci.yml (lint+typecheck+build) and deploy.yml (GHCR + SSH)
- .env.example documenting all required variables
- Fixed docker-compose issues: Studio image tag, Kong port conflict (8001),
  internal role passwords init script, Realtime METRICS_JWT_SECRET/APP_NAME
