Replace Redux + Redux-Saga with React Query (useMutation/useQuery) for
server state and React Context for UI/form state across all modules:
login, registration, forgot-password, reset-password, progressive-
profiling, and common-components.
Port of master commits 0d709d15 and 93bd0f24, adapted for
@openedx/frontend-base:
- getSiteConfig() instead of getConfig()
- useAppConfig() for per-app configuration
- @tanstack/react-query as peerDependency (shell provides QueryClient)
- CurrentAppProvider instead of AppProvider
Also fixes EnvironmentTypes circular dependency in site.config.test.tsx
by using string literal instead of enum import.
