feat: customer full-field display (raw_json + cloud-matching list + all-fields drawer)

Backend:
- CustomerOut now exposes raw_json (verbatim upstream friend record) so the
  frontend can render every 云客 field without per-field structured columns.
- The verbatim blob round-trips via from_attributes; no model change needed.

Frontend:
- CustomerList table mirrors the 云客 客户列表 column set (头像/微信昵称/微信号/
  备注/真实姓名/手机/性别/地区/描述/销售员工/部门/来源/添加方式/添加时间/最近
  聊天/消息数/渠道). A readField helper reads the structured column first and
  falls back to raw_json.<camelCase>.
- Row click opens an all-fields drawer (right side) rendering EVERY field of
  the record with Chinese labels, grouped (基本信息/联系方式/归属员工与部门/时间
  与来源/消息统计/好友状态/其他). Timestamps format to local datetime, flags
  render 是/否, image URLs render as el-image thumbnails, empty values show —.
- New src/utils/customerFields.ts holds the camelCase→中文 label map, the
  structured-column alias map, group definitions, and value-type formatters;
  unknown raw_json keys auto-flow into an 其他 section so new upstream fields
  surface without code changes.
- Drawer 查看聊天记录 action navigates to /chat/:channel/:ownerId/:talkerId
  (owner_account_id + friend_id + channel), preserving the existing path.
