feat: QR code pdf bundler

[natalierobbins]

📄 Description

QR code generation

• Updated QR codes to only encode survey code instead of entire URL, in line with bug: QR code redirect fix #118

PDF generation

• Instead of printing the window, the client now makes a temporary PDF blob with explicit styling that is constant across all devices. This will hopefully fix formatting bugs we are experiencing with printing

  • Included retry + backoff in case of slow PDF load. Worst case, instead of auto printing, the user can download the blob onto their device and manually print
  • The blob is temporary, so if the user waits to long, they will just have to re-click Print

• Print upon survey completion

• Print from Survey Details page
