Publish checks

Before going live, the campaign editor runs a four-step health check so you don't ship a broken widget. The checks live behind the /app/api/publish-checks endpoint and are visible from the campaign edit screen.

Field	Description
Campaign is Active	Status is Active, not Draft or Paused.
Products valid	All upsell products are `ACTIVE` and have available inventory (or don't track inventory).
App embed enabled	The Summer Upsell embed is toggled on in the live theme's `config/settings_data.json`.
App block placed	The matching widget block (e.g. ✨ Summer: FBT Bundle) is present in the right template (product or cart JSON).

The endpoint is auth-gated to the admin session; merchants can't call it from the storefront. The campaign edit screen surfaces any failing check as a warning before you save.
