Introduce full admin user listing/detail endpoints and a forced password-change flow. Backend: make CurrentUserResponse.UserName nullable and add ToCurrentUserResponseAsync extension; AppUserController now exposes GET /auth/user (list) and GET /auth/user/{id} (detail) using UserManager and Admin-only policy; AuthController uses the new mapper and after successful password change clears MustChangePassword, updates UpdatedAt and persists changes (with error handling) before updating security stamp. Frontend: add admin users pages (list + detail), ChangePassword page and route, adminUsers and enhanced authSession services (typed responses, changePassword API, error mapping), router guard to redirect users with mustChangePassword=true to the change-password flow, and show success banner on login after password change. UI tweaks: separate admin section in sidebar, add password-change entries in account menu, footer sizing fixes, and various layout/UX improvements. These changes enable admin account management and enforce secure password updates across the app.
Switch user admin handling from an AppUser boolean to ASP.NET Identity roles. Removed AppUser.IsAdmin and related configuration/model entries; added migration ReplaceIsAdminWithRoles to copy Users.IsAdmin=true into a persistent admin role and drop the IsAdmin column. CurrentUserResponse now exposes roles (string[]), AuthController returns ordered roles from UserManager, and IdentitySeedService now ensures the admin role exists and assigns/creates an initial admin user in that role. Program.cs registers an Admin-only policy (PolicyNames/RoleNames), adjusts cookie auth events to return 401/403 for API requests, and wires up authorization. Frontend updated to use roles: authSession normalizes roles, adds hasRole and ROLE_ADMIN, router and layout support meta.requiredRoles, and new Forbidden and AdminUsers pages/route are added. codexInfo.md updated to reflect the migration to role-based auth.
Introduce authentication API: add AuthController with login, logout and me endpoints using SignInManager/UserManager; add LoginRequest and CurrentUserResponse DTOs. Login enforces active users, updates UpdatedAt on success, and returns localized messages. Also change default seed admin password from "Hoard" to "HoardPassword".
