feat: add chart type selector with candlestick, line, and bar charts

Browse Source 
- Add chart type selector with 3 chart types: candlestick (default), line, and bar

- Fix data format conversion when switching between OHLC and simple {time,value} formats

- Fix line chart refresh to use update() instead of setData() to preserve chart data

- Remove area chart type and AI Insight/refresh buttons

- Improve data handling in loadData, loadNewData, loadHistoricalData, and switchChartType methods
