/**
 * 获取单点样式
 * 支持 symbol 数组配置（icon + text + circle + shape），或单个 symbol 配置
 * 若 symbol 为空则显示蓝色圆点
 *
 * @example
 * // 单个图标配置
 * { symbol: { url: '/path/to/icon.png', scale: 1 } }
 *
 * // 圆点样式配置
 * { symbol: { type: 'circle', radius: 8, fillColor: '#ff0000', strokeColor: '#ffffff', strokeWidth: 2 } }
 *
 * // 规则图形样式配置（三角形）
 * { symbol: { type: 'shape', points: 3, radius: 10, fillColor: 'red', strokeColor: 'black', strokeWidth: 1 } }
 *
 * // 规则图形样式配置（正方形，旋转45度）
 * { symbol: { type: 'shape', points: 4, radius: 10, angle: Math.PI / 4, fillColor: 'blue' } }
 *
 * // 规则图形样式配置（五角星）
 * { symbol: { type: 'shape', points: 5, radius: 12, radius2: 6, fillColor: 'gold', strokeColor: 'orange' } }
 *
 * // 规则图形样式配置（十字形）
 * { symbol: { type: 'shape', points: 4, radius: 10, radius2: 0, strokeColor: 'red', strokeWidth: 2 } }
