refactor: Update manifest.json for improved security and functionality

- Revise extension description to better reflect its purpose in protecting against phishing and malicious links.
- Adjust permissions to include 'tabs' and 'webNavigation' while removing 'activeTab' and 'alarms'.
- Simplify host permissions to allow access to all URLs.
- Enhance content security policy to allow connections to specific external resources.
