feat: 改进5xx错误熔断机制和重置状态功能

## 熔断机制优化
- 将5xx错误阈值从3次提升到10次，减少误触发
- 缩短临时错误恢复时间从60分钟到5分钟
- 支持所有5xx状态码(500-599)的统一处理

## 重置状态功能完善
后端 resetAccountStatus 新增清除:
- tempErrorAt 字段 (temp_error状态)
- sessionWindowStart/sessionWindowEnd 字段
- 5xx_errors Redis计数键

前端优化:
- 重置成功后强制刷新 loadAccounts(true)
- 避免缓存导致的状态显示不一致
