CRITICAL: Temporarily disable Keycloak to restore application functionality

- Disable Keycloak integration in authentication middleware
- Update useUnifiedAuth to only use Directus authentication
- Rebuild login page with only Directus auth form
- Remove all Keycloak references that were causing JavaScript errors
- This restores the application to working state with Directus auth only

Application should now load and function normally. Keycloak can be re-enabled later once issues are resolved.
