fix(wechatmp): support local file:// images in send

Browse Source 
Agent-generated images are sent as IMAGE_URL with a file:// path, but the wechatmp channel always used requests.get, which fails on file:// with InvalidSchema. Now read local files directly (file:// or local path) and fall back to HTTP download for remote URLs, in both passive and active reply modes.
