new /api/desktop/content/assets endpoint with the desktop Bearer token
so editor images keep rendering across token rotations.

Introduce a reusable helper that produces upload-ready blobs for
adapters that share the same image-asset semantics (dongchedi,
sohuhao, wangyihao, weixin-gzh, zol). Centralizes URL candidate
expansion and passthrough mime detection so each adapter focuses on
its own publish protocol.
