[UI/Bug] Missing "Template type" (ISO type) field in "Upload ISO from local" modal

[MertkanOzlu]

problem

When uploading an ISO via the "Upload ISO from local" modal, the "Template type" selection field is missing.
In comparison, the "Upload Template from local" modal includes the Template type dropdown (USER, VNF, SYSTEM, BUILTIN, ROUTING). Because this is missing for ISO uploads, the ISO is not assigned the proper type, causing errors and forcing us to manually update the database table (vm_template) to set the type to USER.

versions

• CloudStack: 4.19 (or latest main)

The steps to reproduce the bug

1. Navigate to Images -> ISOs.
2. Click "Upload ISO from local".
3. Observe that the "Template type" field is missing.

What to do about it?

The "Upload ISO from local" form/modal should include the "Template type" selection field (similar to "Upload Template from local") to allow selecting or properly defaulting the ISO type to 'USER'.

This looks related to the ISO vm_template.type = NULL regression previously reported in #12104 and fixed by #12151 / c3d6a8c.

There is an important version difference, though: #12104 was a 4.22 regression. The reporter there confirmed 4.21 worked before upgrading to 4.22.

I checked the 4.19 source and current 4.20 branch, and ordinary local ISO uploads already resolve to TemplateType.USER there. Current main also explicitly resolves GetUploadParamsForIsoCmd to USER.

So I don't think adding a UI templatetype selector is the right fix. The ISO upload APIs do not expose that parameter, and the backend is already expected to assign USER.

@MertkanOzlu, could you confirm the exact CloudStack version/build you reproduced this on, and whether vm_template.type is actually NULL immediately after a fresh local ISO upload?

That should tell us whether there is a backend regression here and, if so, whether it matches #12104.
