SAML ACS URL does not update after site URL change without server restart (v2.5.305)

[oshinko]

Description

When changing the site URL from the admin panel in Wiki.js v2.5.305, the SAML ACS URL for the SAML 2.0 strategy (e.g., /login/00000000-0000-0000-0000-000000000000/callback) appears to update correctly in the settings.

However, after this change, attempting to log in using SAML authentication with our Identity Provider (IdP) fails. Error messages indicate that the AssertionConsumerServiceURL in the SAMLRequest generated by Wiki.js still contains the old site URL. Only after restarting the server does the SAMLRequest include the updated ACS URL, allowing successful login.

Steps to Reproduce

1. Set up the SAML 2.0 strategy and confirm that login via SAML works successfully.
2. Change the site URL via the Wiki.js admin panel.
3. Attempt to log in again using SAML.
4. Check the AssertionConsumerServiceURL in the SAMLRequest sent to the SAML IdP and observe that it still contains the old URL.
5. Restart the Wiki.js server.
6. Attempt to log in again using SAML, and confirm that the login now succeeds with the updated ACS URL.

Expected Behavior

The AssertionConsumerServiceURL in the SAMLRequest should update immediately after changing the site URL in the admin panel, without requiring a server restart.

Actual Behavior

The AssertionConsumerServiceURL remains outdated until the server is restarted, causing SAML login attempts to fail.
