refactor(bf-bot): 插件重构为 handlers/services/utils 分层，资源归入 res/

- 旧平铺模块（data/data_utils/database_op/image_builder*/get_bf6_data/
  gametools_bf6/bf6_data/img_utils）拆分为 handlers（绑定/查询）、
  services（fetchers/processing/query）、utils（渲染/参数）分层；
  新增 repository.py / config.py / paths.py
- 字体/图片/模板资源迁入 res/，新增 BF2042 卡面素材（bg/object_icon 等）
- browser_ext/：BF2042 扩展捕获桥（WS 直连兜底通道）源码入库
- 新增 hexi/web/src/plugins/bf_bot 前端管理页
- 新增 tests：test_bf_bot_helpers / repository / tracker_api
