Subject: [PATCH] feat: push OIDC config to provisioned server for SSO login

After provisioning a server, pushes Logto Traditional Web App
credentials (client ID + secret) via the server's OIDC admin API.
This enables SSO: users authenticated via Logto can access the
server dashboard without a separate login.

Reads tradAppSecret from bootstrap JSON via LogtoConfig.
