Security: Remove console logging of sensitive information in frontend

[NahomAlemu]

Description

Several components log sensitive information to the browser console, including API URLs, file objects,
and error details. This exposes infrastructure details and could leak sensitive data in production.

Tasks

Tasks:

• Remove console.log in LoginWindow.tsx
• Remove file logging in CoverPhotoDialog.tsx
• Consider creating a frontend logger utility matching backend pattern
• Ensure no sensitive data logged in production
