feat: add interactive abacus display to guide reading section

- Added InteractiveAbacus component for educational demonstration
- Integrated abacus display at bottom of reading section in guide
- Removed click detection functionality as requested
- Added preset buttons for value demonstration
- Enhanced guide with step-by-step interactive practice section
- Cleaned up data attributes and click handling code
