feat: load and cache Ollama show data per model with clickable model details

- Add GET /api/v1/models/{model_name}/show endpoint (proxy to Ollama /api/show)
- Worker now fetches show data for each model during model list sync
- Persist show details in localStorage under llm_monitor_models.showByModel
- Make model cards clickable to display cached show details in a dedicated panel
- Keep UI updates incremental without full page reload
- Add tests for show endpoint and OpenAPI path
- Update README and PRD with show-flow and click-card behavior
