Add debug logging for ChartJS detection and remove preview logic

Changes:
1. Added comprehensive debug logging:
   - Log visualizerAI.chart_library on page load
   - Log chart_library being sent in AJAX request
   - Show library name in welcome message (Chart.js vs Google Charts)

2. Removed preview logic - always auto-apply:
   - Removed detectActionIntent function
   - All AI configurations now auto-apply immediately
   - Configs are merged with existing settings (safe)
   - No more "preview" step or "apply" confirmation needed

This will help debug why ChartJS charts aren't being recognized,
and improves UX by removing unnecessary preview step.
