fix/offline-deploy-review-comments

- Replace curl with wget --spider in minio healthcheck (more portable on minimal images)
- Default LLM_API_BASE_URL to Ollama local endpoint instead of OpenAI public API
- Pin minio/minio and minio/mc to specific release tags (non-deterministic latest removed)
- Allow VITE_API_BASE_URL to be overridden via .env using ${VAR:-default} pattern
- Loop over DOCKERHUB_IMAGES array to save tars instead of hardcoding image names
