Subject: [PATCH] fix: serverless adapter binary body support, hide phone
 number in register
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Keep body as Buffer instead of utf8 string for multipart/form-data
- Set content-length header for multer compatibility
- Phone authorization shows '已授权' instead of actual number
