ℹ️ About the PR

This PR simplifies and optimizes the logic for modifying the Content-Security-Policy (CSP) header in the Electron app. The refactor replaces repetitive replace calls with a dynamic and scalable approach using a replacements object and a reduce function.

Key Changes:

• Replaced repetitive string replacement logic with a loop over a replacements object.
• Improved readability by encapsulating logic in the modifyCSPHeader function.
• Reduced lines of code for better maintainability and scalability.
• This change is non-breaking and ensures the behaviour remains consistent while improving code quality.

🖼️ Testing Scenarios / Screenshots

Manual Validation:

• Opened the Electron app and verified that the CSP headers were correctly updated to include BROWSER_SYNC_HOST in default-src, script-src, connect-src, and other policies.

Debugging Tools:

• Used electron-debug to confirm that headers are applied without errors during runtime.

Regression Testing:

• Ensured no existing functionality is broken by the refactor.

Before & After Comparison:

• No UI/visual changes; this is an internal code improvement. Functionality remains the same.
