Title

Fix models page display, analytics dashboard, and button functionality

Description

## Summary

This PR fixes critical issues with the models page, analytics dashboard, and implements full button functionality in the Models Library.

### Changes

**1. Models Not Showing After Training (Issue #1)**
- ✅ Training jobs now save model weights using Tinker SDK after completion
- ✅ Model metadata (checkpoint path, training config, metrics) stored in `saved_models`
- ✅ Models page fetches both trained and base models
- ✅ Trained models display at the top with "fine-tuned" badge

**2. Analytics Dashboard Empty (Issue #2)**
- ✅ Created new analytics API endpoints:
  - `/api/analytics/summary` - aggregate metrics (total models, training jobs, success rate, GPU hours)
  - `/api/analytics/training-runs` - historical training data
- ✅ Frontend fetches and displays analytics with auto-refresh every 5 seconds
- ✅ Shows real-time training job statistics and metrics

**3. Models Library Button Functionality (Issue #3)**
- ✅ **Test in Playground**: Navigates to Playground with model pre-selected
- ✅ **Export Model**: Copies checkpoint path to clipboard with toast notification
- ✅ **Delete Model**: Double-click confirmation with visual feedback (fine-tuned models only)
- ✅ All buttons work in both model card and details sidebar views

### Files Changed (7 files, +460 insertions, -39 deletions)

**Backend:**
- `backend/routes/training.py` - Save model weights after training completes
- `backend/routes/analytics.py` - New analytics endpoints (131 lines)
- `backend/main.py` - Register analytics router

**Frontend:**
- `frontend/src/views/ModelsLibrary.tsx` - Fetch trained models, implement button handlers
- `frontend/src/views/Analytics.tsx` - Fetch and display analytics data
- `frontend/src/views/Playground.tsx` - Support pre-selected models
- `frontend/src/store/useStore.ts` - Add selectedPlaygroundModel state

### Technical Details

**Model Persistence Flow:**
```python
# backend/routes/training.py:170-197
checkpoint_path = await training_client.save_weights_async(name=model_name)
saved_models.append({
    "name": model_name,
    "checkpoint_path": checkpoint_path,
    "training_config": {
        "rank": config.rank,
        "learning_rate": config.learning_rate,
        "num_steps": config.num_steps,
        "training_type": config.training_type
    },
    "final_metrics": job["metrics"]
})

Analytics Aggregation:

  • Calculates success rate, GPU hours, model count from training jobs
  • Transforms training jobs into display-friendly format
  • Real-time updates via polling (5-second interval)

Button Event Handling:

// Proper event propagation handling
onClick={(e) => {
  e.stopPropagation()
  handleTestInPlayground(model)
}}

How It Works

Training → Models Flow:

Training Completes → Save Weights (Tinker SDK) → Add to saved_models →
Frontend Fetches /api/models/ → Displays in Models Library ✅

Analytics Flow:

Training Jobs → Aggregate Metrics → /api/analytics/summary →
Frontend Auto-refresh → Display Cards & Charts ✅

Playground Integration:

Click "Test in Playground" → Set selectedPlaygroundModel (Zustand) →
Navigate to Playground → Auto-select Model ✅

Testing Checklist

  • Models appear in Models Library after training completes
  • Analytics dashboard shows correct metrics and training runs
  • "Test in Playground" button navigates and pre-selects model
  • "Export Model" button copies checkpoint path to clipboard
  • "Delete Model" button requires confirmation and removes model
  • All buttons work in both list view and sidebar
  • Console logging added for debugging
  • No TypeScript/build errors

Screenshots/Demo

Models Page:

  • Trained models appear with "fine-tuned" badge
  • Base models listed below
  • Performance metrics (loss) displayed

Analytics Dashboard:

  • 4 metric cards: Total Models, Training Jobs, Success Rate, GPU Hours
  • Training runs table with loss, steps, duration
  • Auto-refreshes every 5 seconds

Button Functionality:

  • Play button → Playground navigation
  • Download button → Toast notification with checkpoint path
  • Delete button → Red highlight on first click, deletion on second click
