Fix step definition popup for mobile and escaped quotes

- Replace hover-based Tooltip with click-based popover for mobile support
- Fix pattern extraction regex to handle escaped apostrophes (e.g., l'écran)
- Add dashed underline (1.3px) to indicate clickable steps with definitions
- Enable definitions mode by default
- Regenerate stepDefinitions.ts with correct patterns
