Add Roboto font family and update PDF generation to use custom fonts

- Added Roboto font files to the Docker image and specified their location.
- Updated the PDF generation code to use the Roboto font instead of Arial.
- Enhanced the PDF output by including additional font styles (Bold, Italic, etc.) for better formatting.
- Created a new directory for fonts in the Docker container to manage font files effectively.
