fix: remove scrollIntoView and use scrollTo consistently
- Replaced scrollIntoView with scrollTo({ top }) to avoid page scroll - Added offset = 0 default value for offset parameter - Simplified scrollTo implementation to always use scrollTo - Updated tests to check scrollParam instead of scrollIntoViewElement 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
