feat: initialize panel access before linking Minecraft accounts

Configure connection and storage before creating or resuming the one-time Owner login. Remove Minecraft prerequisites from setup and preserve established login credentials.

Let staff preview and confirm roles from configured authentication sources using the existing account-link storage and game UUID mapping. Retain in-game code proof for players, add client-version and lobby guidance, and support NodePort passkey origins.
