fix: detect candle interval dynamically instead of hardcoded 60s

Browse source 
Replace the hardcoded 60-second assumption in CandleChart.tsx with
dynamic interval detection: compute interval as candles[1].time -
candles[0].time when at least 2 candles are available, fall back to
60 otherwise. Used for span-to-prediction-time mapping iteration.

Marks task 8.6 as done in tasks.md.
