Describe the bug

When users sign up with a social the metadata gets applied properly. When they link it later the metadata does not get updated properly.

So it happens on register but not on update settings. I think it's because this PR

https://github.com/ory/kratos/pull/2569

Did not address updating social logins from settings.

Reproducing the bug

• Create a user with email
• Link an OIDC method that has a valid mapping in settings

Additional Context

No response

Start by comparing the registration flow, where social metadata works, with the settings flow used to link an OIDC method. Read PR #2569 for the related implementation and identify whether the settings update path applies the configured mapping. Done means the reproduction steps produce the same mapped metadata after linking, with regression coverage for both flows.
