chore: add Coolify deployment scaffolding (Dockerfiles, prod compose, git hygiene)

- apps/api/Dockerfile: build NestJS, run prisma migrate deploy on start
- apps/web/Dockerfile + nginx.conf: build Vite, serve static, proxy /api -> api
- docker-compose.coolify.yml: full prod stack (postgres, redis, minio, keycloak, api, web)
- .dockerignore / .gitignore / .gitattributes
