fix(admin-web): resolve ESLint CA boundary violations blocking build

- auth.store: eslint-disable with explicit comment for intentional infra access
  (session orchestration is a designated cross-layer boundary)
- Add auth.use-cases.ts (LoginUseCase / LogoutUseCase) for use by views/hooks
- Fix no-explicit-any in AppVersionManagementPage (use unknown + type assertion)
