Bootstrap monorepo: Hono API, React PWA, Drizzle DB, CI/CD

Sets up the initial project structure for groombook/groombook:

- pnpm monorepo with apps/api (Hono + TypeScript), apps/web (React + Vite + PWA), packages/db (Drizzle ORM), packages/types (shared types)
- Core DB schema: clients, pets, services, appointments, staff with CNPG-compatible Postgres
- REST API routes for clients, pets, services, appointments with Zod validation
- OIDC auth middleware for Authentik integration
- React PWA with vite-plugin-pwa, service worker, offline caching, installable manifest
- GitHub Actions CI: lint, typecheck, test, build, Docker image build (groombook-runners)
- Dockerfiles for API (Node.js) and Web (nginx)
- docker-compose.yml for local development
