feat(ops): 增强错误日志管理、告警静默和前端 UI 优化

PR_DESCRIPTION.md

+## 概述
+
+全面增强运维监控系统（Ops）的错误日志管理和告警静默功能，优化前端 UI 组件代码质量和用户体验。本次更新重构了核心服务层和数据访问层，提升系统可维护性和运维效率。
+
+## 主要改动
+
+### 1. 错误日志查询优化
+
+**功能特性：**
+- 新增 GetErrorLogByID 接口，支持按 ID 精确查询错误详情
+- 优化错误日志过滤逻辑，支持多维度筛选（平台、阶段、来源、所有者等）
+- 改进查询参数处理，简化代码结构
+- 增强错误分类和标准化处理
+- 支持错误解决状态追踪（resolved 字段）
+
+**技术实现：**
+- `ops_handler.go` - 新增单条错误日志查询接口
+- `ops_repo.go` - 优化数据查询和过滤条件构建
+- `ops_models.go` - 扩展错误日志数据模型
+- 前端 API 接口同步更新
+
+### 2. 告警静默功能
+
+**功能特性：**
+- 支持按规则、平台、分组、区域等维度静默告警
+- 可设置静默时长和原因说明
+- 静默记录可追溯，记录创建人和创建时间
+- 自动过期机制，避免永久静默
+
+**技术实现：**
+- `037_ops_alert_silences.sql` - 新增告警静默表
+- `ops_alerts.go` - 告警静默逻辑实现
+- `ops_alerts_handler.go` - 告警静默 API 接口
+- `OpsAlertEventsCard.vue` - 前端告警静默操作界面
+
+**数据库结构：**
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| rule_id | BIGINT | 告警规则 ID |
+| platform | VARCHAR(64) | 平台标识 |
+| group_id | BIGINT | 分组 ID（可选） |
+| region | VARCHAR(64) | 区域（可选） |
+| until | TIMESTAMPTZ | 静默截止时间 |
+| reason | TEXT | 静默原因 |
+| created_by | BIGINT | 创建人 ID |
+
+### 3. 错误分类标准化
+
+**功能特性：**
+- 统一错误阶段分类（request|auth|routing|upstream|network|internal）
+- 规范错误归属分类（client|provider|platform）
+- 标准化错误来源分类（client_request|upstream_http|gateway）
+- 自动迁移历史数据到新分类体系
+
+**技术实现：**
+- `038_ops_errors_resolution_retry_results_and_standardize_classification.sql` - 分类标准化迁移
+- 自动映射历史遗留分类到新标准
+- 自动解决已恢复的上游错误（客户端状态码 < 400）
+
+### 4. Gateway 服务集成
+
+**功能特性：**
+- 完善各 Gateway 服务的 Ops 集成
+- 统一错误日志记录接口
+- 增强上游错误追踪能力
+
+**涉及服务：**
+- `antigravity_gateway_service.go` - Antigravity 网关集成
+- `gateway_service.go` - 通用网关集成
+- `gemini_messages_compat_service.go` - Gemini 兼容层集成
+- `openai_gateway_service.go` - OpenAI 网关集成
+
+### 5. 前端 UI 优化
+
+**代码重构：**
+- 大幅简化错误详情模态框代码（从 828 行优化到 450 行）
+- 优化错误日志表格组件，提升可读性
+- 清理未使用的 i18n 翻译，减少冗余
+- 统一组件代码风格和格式
+- 优化骨架屏组件，更好匹配实际看板布局
+
+**布局改进：**
+- 修复模态框内容溢出和滚动问题
+- 优化表格布局，使用 flex 布局确保正确显示
+- 改进看板头部布局和交互
+- 提升响应式体验
+- 骨架屏支持全屏模式适配
+
+**交互优化：**
+- 优化告警事件卡片功能和展示
+- 改进错误详情展示逻辑
+- 增强请求详情模态框
+- 完善运行时设置卡片
+- 改进加载动画效果
+
+### 6. 国际化完善
+
+**文案补充：**
+- 补充错误日志相关的英文翻译
+- 添加告警静默功能的中英文文案
+- 完善提示文本和错误信息
+- 统一术语翻译标准
+
