refactor: 提取 HandlerAdapterBase 基类，新增 api_family/endpoint_kind 结构化维度

- 从 ChatAdapterBase 和 CliAdapterBase 提取公共逻辑到 HandlerAdapterBase，
  消除头部处理、异常处理、计费策略等重复代码
- Usage 记录链路全程透传 api_family / endpoint_kind / provider_api_family /
  provider_endpoint_kind 四个结构化字段，替代从 api_format 字符串解析
- 删除冗余的 ClaudeCliNormalizer、GeminiCliNormalizer、ClaudeCliResponseParser、
  GeminiCliResponseParser，改用 data_format_id 回退机制自动复用 Chat 版本
- build_endpoint_url 签名统一扩展 request_data / model_name 参数
- 新增 Alembic 迁移，含历史数据回填
