Phatdoan203/Admin-CKS — reverse-engineered prompt

Please build out the CKS admin app in this repo. I need a working admin site with a clean login page, session handling through the auth service, and a protected dashboard after signing in.

The dashboard can be simple, but it should show the app is connected to the backend, display a few core admin sections, and make it easy to add real CKS management pages later. Make the API service and auth service work together, and have the client call them properly with clear loading and error states.

Please also make the Docker setup run the whole thing locally without manual steps, and add basic setup notes since there’s no README. Keep the UI plain but usable, with sensible navigation, logout, and no broken pages. If anything is missing, choose practical defaults and leave small comments for where real business logic should be added.
