"Link with <provider>" fails with `Provider with id "Authelia" not found. Available providers: [credentials, authelia]`

On the v3 profile page my account already shows as linked to my OIDC provider, but a "Link with <Provider>" button is offered as well. Clicking it returns "Server error. There is a problem with the server configuration. Check the server logs for more information." Nothing shows up in the identity provider's logs even with debug logging on there, and Storyteller only logged something once I enabled debug logging on its side.

Resolution: It is a casing bug in Storyteller, not a server or identity-provider misconfiguration. The link button sends the provider's display name (Authelia) as the provider id, while the registered id is lowercase, so the auth layer rejects it: [auth][error] Error: Provider with id "Authelia" not found. Available providers: [credentials, authelia]. There is nothing to change on the identity provider side, and the button should not be presented at all for an account that is already linked. To confirm you are hitting the same thing, toggle debug logging from the logs view in settings (it applies immediately but does not persist across restarts) and look for that [auth][error] line. Your existing account link continues to work; just don't use the redundant link button until a build with the id casing corrected is out.
