Fix Svelte image module reading the wrong resource field

[krixkrix]

Summary

ModuleImage.svelte read module.imageresourceuuid, but AMCModule_Image.js sets imageresource, so no <image> content rendered in the Svelte client.

 imageURL
-  module.imageresourceuuid ? app.getImageURL(module.imageresourceuuid) : ''
+  uuid = module.imageresource
+  if (!uuid || uuid === nullUUID || !app) return ''
+  return app.getImageURL(uuid)

The null-UUID check matches the BuildList/PartList/ExecutionList thumbnails. Without it, the core default 00000000-… would request a broken image.

Evidence

WidgetTest, Dashboard → "Machine View" (<image resource="ui_logo">), Svelte client:

• Before: heading only, no /api/image request
• After: logo renders at maxheight="80"

Merge Danger

Door: two-way

Blast Radius: Svelte <image> only
