feat(plotly): improve line-basic implementation

- Remove unnecessary pandas import (use simple lists)
- Disable legend for single series (per quality criteria)
- Increase font sizes for better readability at 4800x2700px
- Increase line width from 2 to 3 for better visibility
- Adjust margins for proper layout
