feat(swap): 实现互换交易价格精度控制功能 init

- 添加 swapPricePrecisionHelper.js 工具类处理价格精度格式化
- 新增 swappriceprecision.js 配置文件定义各类金融产品的精度规则
- 在 EodPositionRisks.cshtml 和 SwapIncome.cshtml 中引入新的价格格式化脚本
- 替换原有的价格格式化函数为基于产品类型的动态精度控制
- 移除旧的价格验证和标准化逻辑，改用新的精度控制机制
- 添加 vue-swap-price-input 组件用于精确的价格输入控制
- 更新 Controller 中的价格处理逻辑以支持新精度格式化方式
