Map dongchedi adapter failures (raw "server exception" or
dongchedi_platform_exception) to a Chinese prompt steering the user to
the dongchedi backend, so renderer/admin views and desktop-task error
payloads no longer surface the opaque platform message.
Expose tenant-authenticated publish task list and retry endpoints so the
admin web can show desktop publish state without an Electron bridge, and
register a `shengxintui://` deep-link so the page can hand off to the
desktop client workbench.
