fix: resolve admin session infinite reload loop and sync auth state

- Prevent infinite redirection loop by clearing oidc-client user state on 401 errors.
- Sync apiClient request interceptor to use userManager.getUser() for reliable token retrieval.
- Add extensive console logs for better session issue diagnosis.
- Fix TS error in LoginPage by updating button variant.
- Revert 'ae03fe1' (updated playwright fixtures to real domain) as requested.
