v4.4.3 BA7OPF Feature Build 2

匹配页与雷达页改进

• 匹配页：
  • 底部导航新增“匹配”入口与新的双曲线图标
  • 优化双方位置输入与匹配结果展开布局
  • 修正最小仰角过滤：双方最大仰角必须分别超过各自阈值才进入结果，避免 90° 仍搜到、45° 展开后无曲线
• 双方雷达：
  • 从匹配页进入雷达时正确匹配主过境窗口
  • 双方雷达过境结束后自动退出
  • 普通雷达入口会清空双方轨迹，避免残留叠加

Mutual page and radar improvements

• Mutual page:
  • Added the “匹配” bottom-tab entry with a new two-curve icon
  • Improved two-station input and expanded result-card layout
  • Fixed minimum-elevation filtering: both stations must exceed their own thresholds before a result is shown, preventing 90° false matches and empty 45° charts
• Dual-station radar:
  • Correctly resolves the main pass window when entering Radar from a mutual pass
  • Automatically exits the dual-station radar after the mutual pass ends
  • Clears dual-station overlay data on normal Radar entry to avoid stale tracks
