fix: button detection with text alignment

Added data-button attribute selector to TipTap button parseHTML.
This ensures buttons are properly detected when text alignment is
applied, as alignment may affect CSS class detection.

Priority order:
1. a[data-button] - most reliable
2. a.button
3. a.button-outline
