hailin 5dfef3172e fix(kline): 修正最新K线居中逻辑 
K线从屏幕左边开始画，通过leftOffset偏移使最新K线显示在展示区中央。

hailin ccbea74f87 fix(kline): 稀疏数据时让最新K线居中而非整组居中 
修正居中逻辑：当K线数量少时，让最新的那根K线（最右边）显示在屏幕中央，而不是让整个K线组居中。

hailin f1b2ec7ede fix(kline): 稀疏K线数据时居中显示 
当K线数量较少（如1分钟图刚开始）时，K线不再拉伸填满屏幕，
而是使用默认宽度并在可用区域内水平居中显示。

hailin a97e0b51b8 feat(kline): 首次加载时让最新K线居中显示 
- 新增 _scrollToCenter() 方法，计算让最新K线居中的滚动位置
- 初始化时调用 _scrollToCenter() 替代 _scrollToEnd()
- 如果K线总宽度小于屏幕宽度，不滚动，从左开始显示
- 保留 _scrollToEnd() 方法供刷新按钮等场景使用

hailin 928d6c8df2 refactor(frontend): 优化K线图显示与交互体验 
主要改动:
1. 隐藏技术指标 - 暂时隐藏MA/EMA/BOLL主图指标和MACD/KDJ/RSI副图指标
   - 保留全部代码，便于未来恢复（取消注释即可）
   - 调整高度分配：主图75%、成交量25%

2. 修复单指滑动(pan)问题
   - 移除错误的scale阈值检测 `(details.scale - 1.0).abs() > 0.01`
   - 改用 `pointerCount > 1` 区分单指滑动和双指缩放
   - 单指滑动现可正常左右拖动K线图

3. 优化首次加载显示
   - 新增 `_initialized` 标志控制初始化时机
   - 新增 `_initializeCandleWidth()` 方法动态计算K线宽度
   - K线首次加载时自动填满可视区域宽度
   - 数据量变化时自动重新初始化

技术细节:
- 使用 LayoutBuilder 获取实际图表宽度后再初始化
- 通过 postFrameCallback 确保在布局完成后执行初始化
- K线宽度限制在 3.0-30.0 像素范围内
