[BUG] Do not show missing message for Rancher prime + airgapped env

[a110605]

Setup

• Rancher version: 2.13.1 / 2.14.1 Rancher Prime
• Rancher UI Extensions: harvester ui extension
• Browser type & version: Chrome

Note. there is a compressedEndpoint issue when installing extension from rancher/ui-plugin-catalog on rancher 2.14.1 prime. According to the slack thread, the issue will be fixed in 2.14.2.

Describe the bug
In Rancher Prime, we check harvester repository missing with exactly matches with

 OFFICIAL: {
    NAME:   'rancher-ui-plugins',
    URL:    'https://github.com/rancher/ui-plugin-charts',
    BRANCH: 'main',
  },

But for airgapped Prime user, they import mirrored rancher/ui-plugin-catalog in extension page and unexpected missing message pops up.

To Reproduce

1. Setup a Rancher Prime.
2. Import rancher/ui-plugin-catalog in extension page
3. Install harvester ui extension
4. Go to Virtulization Mgmt page.

Result
The missing message is pop up and update button pop up.

Expected Result
There shouldn't show any missing message and update button

🎯 Agentic Issue Triage

Summary: In airgapped Rancher Prime environments, users import a mirrored repo (rancher/ui-plugin-catalog) instead of the official rancher/ui-plugin-charts GitHub URL. The UI checks for the official repo URL via an exact match, so the mirrored repo is not recognized and a spurious "missing repository" banner is shown on the Virtualization Management page — even though the harvester extension is properly installed.

📍 Root Cause Analysis

The check at shell/pages/c/_cluster/uiplugins/index.vue:158 is:

const uiPluginsRepoNotFound = isRancherPrime() && !this.repos?.find((r) => r.urlDisplay === UI_PLUGINS_REPOS.OFFICIAL.URL);

UI_PLUGINS_REPOS.OFFICIAL.URL is hardcoded to https://github.com/rancher/ui-plugin-charts in shell/config/uiplugins.js.

Airgapped users use rancher/ui-plugin-catalog (a mirrored/internal registry variant), which has a different URL. The === exact-match means the official repo is "not found" even when a valid equivalent is present.

A similar pattern may exist in:

• shell/dialog/AddExtensionReposDialog.vue (hasRancherUIPluginsRepo)
• shell/pages/c/_cluster/uiplugins/__tests__/AddExtensionRepos.test.ts

🔧 Suggested Fix Approaches

Option A — Allow alternate/mirrored repo URLs

Add a known-alternate URL (e.g. rancher/ui-plugin-catalog) to UI_PLUGINS_REPOS.OFFICIAL or a new OFFICIAL_AIRGAP key, and update the check to accept either:

const officialUrls = [UI_PLUGINS_REPOS.OFFICIAL.URL, UI_PLUGINS_REPOS.OFFICIAL_AIRGAP?.URL].filter(Boolean);
const uiPluginsRepoNotFound = isRancherPrime() && !this.repos?.find((r) => officialUrls.includes(r.urlDisplay));

Option B — Pattern/regex-based matching

Use a regex or partial match (e.g. url.includes('ui-plugin-catalog') || url.includes('ui-plugin-charts')) instead of strict equality.

Option C — Label-based detection

In shell/utils/uiplugins.ts there is already a label-based approach (UI_PLUGIN_LABELS.CATALOG_IMAGE) for matching repos. Consider extending the "official repo found" check to also inspect repository labels — airgapped mirrors likely carry the same catalog image label.

🧪 Reproduction Steps

1. Set up Rancher Prime 2.14.1 in an airgapped environment.
2. On the Extensions page, import rancher/ui-plugin-catalog (the mirrored catalog).
3. Install the Harvester UI Extension from that repo.
4. Navigate to Virtualization Management.
5. Observe the unexpected "missing repository" banner appears.

Expected: No banner — the mirrored catalog satisfies the requirement.

✅ Sub-task Checklist

• Confirm which URL/identifier rancher/ui-plugin-catalog presents as urlDisplay in the store
• Update UI_PLUGINS_REPOS.OFFICIAL (or add an alternate) in shell/config/uiplugins.js
• Fix the exact-URL check in shell/pages/c/_cluster/uiplugins/index.vue (showAddReposBanner computed)
• Fix the same pattern in shell/dialog/AddExtensionReposDialog.vue (hasRancherUIPluginsRepo)
• Add/update unit tests in shell/pages/c/_cluster/uiplugins/__tests__/AddExtensionRepos.test.ts
• Verify the Virtualization Management page no longer shows the banner when using ui-plugin-catalog

Acceptance Criteria

Could you add 1–3 concrete, testable acceptance criteria that define what "fixed" looks like? For example:

• When a Rancher Prime user in an airgapped environment installs the Harvester UI extension using rancher/ui-plugin-catalog, no "missing" banner or update button is shown on the Virtualization Management page.
• The fix does not affect the existing behaviour for non-airgapped Prime users.

Feel free to edit the issue body directly to add these, so the issue is ready for engineering triage.
