Deploy prep: Dockerfiles for admin (Next standalone) + scheduler (Bun)

admin/Dockerfile: 2-stage monorepo Next.js standalone (outputFileTracingRoot added to next.config so the bundle traces workspace deps). scheduler/Dockerfile: single-stage Bun runtime, validated by a local docker build. .dockerignore excludes node_modules/.next/.turbo/.git. Build context = monorepo root; runtime env DATABASE_URL + REDIS_URL.
