feat: 优化 Claude 模型缓存费用计算，支持 5 分钟和 1 小时两种缓存类型

- 在 pricingService 中硬编码 1 小时缓存价格（Opus: $30/MTok, Sonnet: $6/MTok, Haiku: $1.6/MTok）
- 更新 usage 捕获逻辑以分别记录 ephemeral_5m 和 ephemeral_1h 缓存 tokens
- 改进费用计算逻辑，正确计算两种缓存类型的费用
- 新增 recordUsageWithDetails 方法支持详细的缓存数据
- 保持向后兼容性，支持旧的数据格式
- 删除测试脚本 test-openai-refresh.js
- 修复 OpenAI token 刷新逻辑
