Improved Statistics and Security Settings

Statistics display now handles missing data gracefully. Security settings on iOS and Android devices are tightened to prevent insecure data transmission and remove unnecessary location permissions.

Improvements

• Statistics screen now safely handles empty or incomplete voting and interest data without errors.

• User vote percentages correctly show zero values instead of missing data.

• Favorite topic display adapts to cases when no personal interests are available.

Security

• Removed empty iOS location permission prompt to avoid unnecessary access requests.

• Blocked Android cleartext network traffic to enhance data transmission security.
