feat: Add URL Share Extension with API integration

- Add ShareViewController with complete URL extraction logic
- Support URL sharing from Safari, Chrome and other apps
- Extract URLs from different content types (URL, plain text, property list)
- Implement direct API call to create bookmarks from share extension
- Add Core Data integration to fetch authentication token
- Include proper error handling and user feedback with alerts
- Support title extraction and user text input for bookmark creation

Technical implementation:
- Handle UTType.url, UTType.plainText, and UTType.propertyList
- Async/await pattern for API requests
- NSDataDetector for URL extraction from text
- Property list parsing for Safari-style sharing
- Loading and success/error alerts for better UX
