Add visibility toggle for picks features and rename Mes choix to Mes picks

- Renamed 'Mes choix' to 'Mes picks' across all pages and JavaScript files
- Added visibility toggle in control panel (Réglages > Visibilité) to control:
  - Display of 'Mes picks' button in navigation
  - Display of 'Bon picks' column in user statistics
- Combined both visibility options into single toggle for simplicity
- Added backend API endpoints for visibility configuration
- Implemented localStorage caching for instant visibility updates
- Fixed flash of content issues when navigating between pages
- Updated stats endpoint to calculate correct picks on-the-fly from current winners
- Renamed 'Bonnes réponses' to 'Bon picks' in user statistics table
