[Bug]: Apps sidebar shows phantom "1" update although no app updates exist

[Sparkfog]

⚠️ This issue respects the following points: ⚠️

• This is not a troubleshooting question, general support matter, or webserver/proxy problem, but likely a bug (if unsure, ask the Community Help Forum).
• This issue is not already reported on Github OR solved at the Community Help Forum (I've searched!).
• I'm using a maintained major version of Nextcloud Server and tested against the latest patch level. (Supported major versions and current patch levels).
• I agree to follow Nextcloud's Code of Conduct.
• I've tried my best to provide clear reproduction steps that someone unfamiliar with this bug could use to reproduce it.

Bug description

The Apps settings sidebar shows a permanent 1 next to Updates, even though there are no app updates available.

Opening Settings → Apps → Updates shows:

No matching apps found

The counter remains after refreshing the page, using a private browser window, restarting the Nextcloud container, and running maintenance:repair.

The backend also reports that no updates are available:

php occ app:update --showonly

Steps to reproduce

1. Log in as an administrator.
2. Open Settings → Apps.
3. Observe that the sidebar shows Updates 1.
4. Open Updates.
5. Observe that the page says No matching apps found.
6. Run php occ app:update --showonly and observe that Nextcloud reports no available updates.
7. Refresh/reopen the Apps page; the 1 counter remains.

Expected behavior

When no app updates are available, the Updates sidebar entry should not show a pending-update count.

The UI should be consistent with occ app:update --showonly.
