Remove deprecated middleware and update component tests for branding and auth enhancements

- Deleted `middleware.disabled.ts` as it is no longer needed.
- Refactored `HeroSection` and `HomePage` tests to align with updated branding and messaging.
- Modified `DemoCredentialsModal` to support auto-filled demo credentials in login links.
- Mocked `ThemeToggle`, `LocaleSwitcher`, and `DemoCredentialsModal` in relevant tests.
- Updated admin tests to use `QueryClientProvider` and refactored API mocks for `AdminPage`.
- Replaced test assertions for stats section and badges with new branding content.
