This pull request improves the visual design of PDF reports generated by the agent. Key enhancements include:

• Improved Font Styling: Clean font hierarchy with modern fonts (Helvetica) for better readability.
• Table Formatting: Alternating row colors, borders, and larger headers for clearer structure.
• Page Layout: Increased white space, centered titles, and optional logos for a more polished look.
• Color Scheme: Soft background colors and enhanced contrast for headers and tables.
