feat: 缓存计费细分、能力匹配优化、用户模型调用计数

1. 缓存创建 tokens 区分 5min/1h TTL，支持按缓存时长差异化计费
   - Usage 表新增 cache_creation_input_tokens_5m/1h 字段
   - Claude handler 解析新格式 (ephemeral_5m/1h, claude_cache_creation_5/1h)
   - 计费规则支持 cache_ttl_pricing 覆盖 cache_creation 价格

2. 能力匹配机制优化
   - COMPATIBLE 能力不再硬过滤，改为排序阶段通过 capability_miss_count 优先级处理
   - cache_1h 改为 COMPATIBLE + REQUEST_PARAM（自动检测请求体中的 ttl=1h）
   - gemini_files 改为 EXCLUSIVE + REQUEST_PARAM（自动检测 fileData.fileUri）
   - 移除前端模型偏好/能力配置 UI（不再需要用户手动配置）

3. 新增用户-模型维度调用次数计数器 (UserModelUsageCount)
   - 原子递增，避免从 Usage 表聚合查询
   - 前端模型目录和用户可用模型列表展示调用次数

4. 其他改进
   - global_model_id 改为必填（NOT NULL），清理孤立模型
   - 模型映射对话框支持从上游获取模型列表并分组折叠
   - 端点测试不再依赖端点启用状态
   - 异步任务页面对普通用户隐藏用户信息列
   - Dashboard 响应式布局断点调整 (sm -> lg)
   - 号池管理仅展示已启用号池的提供商
