Fix chart style issues for candlestick and treemap charts (#26)

* Fix chart style issues for candlestick and treemap charts

- Fix candlestick chart boundary and layout issues:
  * Set boundaryGap to true to prevent chart elements from touching edges
  * Adjust X-axis min/max values for better spacing (-0.2, length-0.8)
  * Increase grid margins (left: 12%, right: 10%) for better text visibility
  * Add volume Y-axis min: 0 to ensure proper volume chart display
  * Set volume bar width to 60% for better visibility

- Simplify treemap chart configuration:
  * Remove leafDepth and upperLabel settings that caused layout issues
  * Remove redundant itemStyle and levels configurations
  * Use ECharts default styling for cleaner appearance and better performance

Fixes #22
