fix(anthropic-cua): use 120px scroll multiplier to match Anthropic xdotool behavior

Anthropic's reference implementation uses xdotool where each scroll_amount
unit equals one scroll wheel click (~120 pixels). Previously:
- TypeScript used the value directly
- Python used a 10x multiplier

Both now use 120x to match Anthropic's expected behavior for AI agents.
