Subject: [PATCH] Configures Tesla OIDC endpoints dynamically

Configures the Tesla OIDC endpoints using the base URL
to dynamically set authorization, token, JWKS URI, end
session, and user info endpoints. This eliminates the need
for a URL override function and centralizes the endpoint
configuration logic.
