"""Round 11 patch — _api_fetch headers ISO-8859-1 sanitize.

修复 import_admin_session 路径下的 fetch RequestInit 抛
"String contains non ISO-8859-1 code point" 错误。

覆盖:
  - 非 Latin1 字符强制 replace 为 '?' + logger.warning
  - None header value 不写入 headers dict(skip)
  - 正常 ASCII 字段不被改写,no warning
  - bytes value decode + sanitize
