feat(passport-photo): SOTA passport photo maker with compliance validation (#64)

* feat(passport-photo): add passport specs database and tool constants

* feat(passport-photo): add MediaPipe FaceMesh landmark detection script

* feat(passport-photo): add TypeScript bridge for face landmark detection

* feat(passport-photo): add API routes with analyze and generate endpoints

* fix(passport-photo): accept landmarks from request body and fix pixel coordinate conversion

- Generate endpoint now accepts landmarks + imageWidth/imageHeight in request body
  instead of re-running AI face detection (makes generate phase instant)
- Fixed bug where normalized landmark coordinates (0-1) were used directly
  as pixel values in crop computation - now properly multiplied by imgW/imgH
- Fixed same bug in pipeline process function

* feat(passport-photo): add UI component with live preview and compliance overlay
