- Fix Flash of Unstyled Content (FOUC) by hiding page until translations load
  - Hide body initially with visibility:hidden
  - Show content after translations are applied to avoid English flash
- Fix authenticated indicator layout with white-space:nowrap
- Add "●" symbol to translation files to prevent disappearance on reload
- Enable network access by binding server to 0.0.0.0 in test config
- Simplify test config API keys to single entry
