feat: export DevCard as PDF for printing and email signatures

[Nareshkumawat-star]

Feature Request

Users want to print their DevCard or attach it to email signatures. Currently there is no PDF export option.

Proposed Solution

• Add "Export as PDF" button on the card profile page
• Generate a print-optimized PDF using puppeteer (backend) or react-pdf (client-side)
• Standard business card sizes: 3.5 x 2 inches (US) and 85 x 55 mm (EU)
• Include QR code, name, title, social links, and profile photo
• Option to download as "DevCard_YourName.pdf"

Affected Platforms

• Web
• Mobile (share sheet to PDF)

Hey @ShantKhatri, just checking in on this PR when you get a chance. Happy to make any changes needed!

Hi @Jai-Shankar1033 , we don't have a card in the web module, so I don't think exporting to the web module will make sense. I can show you the further planning for web in today's community call if you wanna continue work on web module.

Hi @ShantKhatri, thanks for the clarification! I'd love to join the community call
to understand the web module roadmap better. Could you share the call details or
Discord link? I'm happy to close this PR for now and pick up work that fits the
current direction.
