NinaTakangrequested to merge
ninatakang/paulina:feat/T406989/poc-new-statements into main

Add a proof-of-concept "Add information" feature that allows users to visually simulate adding missing biography fields without persisting data. The feature dynamically detects missing fields and provides an intuitive dropdown-based interface following Paulina's design patterns.

  • Add "Add information" button below biography section
  • Implement dropdown showing only missing biography fields
  • Add input field with contextual placeholders
  • Use existing UI components and styling conventions
  • Support internationalization via Jinja2 templating
  • Include proper focus management and interaction states
  • No data persistence - pure UI demonstration only
