952eb7413c feat(ui): add prediction chart rendering with histogram overlay, markers, filtering, and visibility toggle 
- Add histogram series to CandleChart for per-bar prediction colors (15% opacity)
- Add series markers showing label name and confidence % at prediction span starts
- Implement confidence threshold filtering for both histogram and markers
- Implement label type filtering from PredictionPanel checkboxes
- Implement prediction layer visibility toggle (show/hide)
- Add getVisibleCandles method to CandleChartHandle for on-demand prediction fetching
- Pass prediction state props from page.tsx to CandleChart

Tasks 10.1-10.5 complete.

28ebe2c5d1 feat(ui): add prediction state management and PredictionPanel component 
- Create prediction type definitions in src/types/predictions.ts
- Add prediction state management to page.tsx with caching
- Implement PredictionPanel component with:
  - Master visibility toggle
  - Model info display (name, version, type, metrics)
  - Action buttons (Run on Visible, Predict All)
  - Confidence threshold slider
  - Label filter checkboxes with per-class metrics
  - Disagreement filter toggle
  - Prediction summary display
  - Model server offline banner
- Add on-demand and batch prediction fetching
- Implement prediction caching by chart and model version
- Add health polling for inference API (30s interval when offline)
- Ensure annotation tools work independently of prediction API

Tasks completed: 9.1-9.5, 12.1-12.3 (59/78 total)
