Add "Download as PDF" button

[ypratham]

Is your feature request related to a problem? Please describe. Currently, users can create invoices, but there is no option to download the invoice as a PDF. This limits the app's usefulness, as users cannot easily save or share their invoices directly from the application.

Describe the solution you'd like Implement a "Download as PDF" button on the invoice page that allows users to download the generated invoice as a PDF using React PDF. The PDF should replicate the on-screen invoice, including all relevant details like customer information, invoice items, and totals.

Describe alternatives you've considered

Manually using the browser’s print-to-PDF function, but this often leads to inconsistent formatting and layout issues. Additional context React PDF provides a flexible, React-based solution for generating PDFs directly from the application's components. The initial implementation should focus on replicating the current layout with no additional customizations. Future updates can introduce more advanced features.
