feat: implement enhanced conversion tracking for Google Ads
- Add SHA256 hashing for user data to support enhanced conversions - Update trackGoogleAdsConversion to accept optional user data - Add new trackPageViewConversion for automatic event tracking - Replace direct onClick handlers with proper async tracking - Ensure consent is checked before any tracking occurs This addresses the Google Ads warning about implementing in-page code for enhanced conversions instead of relying on automatic detection.
