fix(neware): 修复 submit_auto_export_excel 因 resource=[] 导致 0 下发 + filetype kwarg

问题：
- 日志中 submit_auto_export_excel 收到 resource=[]（工作流本身不传成品电池资源，
  电池由人工搬运），原代码 n = len(resource) = 0 → 整个循环跳过 →
  "共 0 颗电池，成功下发 0 颗"。
- neware_driver.start_test 原来不接收 filetype kwarg，导致 TypeError 阻塞下发。

修复：
1. submit_auto_export_excel 改为由 mount_resource 驱动循环长度：
   - 新签名以 mount_resource 为主，resource/pole_weight/coin_cell_code 均可选
   - 新增 coin_cell_code 入参，coin_id 优先级 coin_cell_code > resource.name > fallback
   - n==0 时提前返回并给出明确错误信息
2. manual_confirm 的返回值与 YAML handles/output 新增 coin_cell_code
   （从已解包的 assembly_data 直接取）
3. submit_auto_export_excel YAML goal/schema/goal_default/handles.input
   新增 coin_cell_code；required 中移除 resource（不再强制）
4. neware_driver.build_start_command / start_test 增加 filetype:int=1 参数，
   动态嵌入 XML backup 配置，消除 TypeError
