Temporary duplicate items after TLS cert request

[DavidePrincipi]

After a TLS certificate has been obtained the page reload temporarily shows duplicate entries.

A minor UI glitch occurs when explicitly requesting a Let's Encrypt certificate from the Settings > TLS Certificates page for a DNS name that has already been requested from an application’s Settings page (e.g., Nextcloud). After the challenge is completed, the UI displays additional unexpected entries—possibly reappearing route entries. Performing a Ctrl+Shift+R refresh resolves the issue.

Steps to reproduce

• Navigate to Settings → TLS Certificates in the NS8 UI.
• Request a Let's Encrypt certificate for a DNS name from the Settings of an application (e.g., Nextcloud).
• Once the certificate is issued, go to Settings → TLS Certificates and explicitly request a Let's Encrypt certificate for the same DNS name.
• Wait for the challenge process to complete.

Expected behavior

The name is added to the default certificate as a SAN.

Actual behavior

• Observe the UI displaying additional unexpected entries (e.g., route entries reappearing).
• Perform a Ctrl+Shift+R refresh, which resolves the issue.

VERIFIED

This bug is not reproducible within the parent's issue test case, because a server-side validator prevents the request of a FQDN already set by an HTTP route.
