feat: integration mlkit Document Scanner pour la prise de photo

Remplace la camera maison par le scanner de documents Google ML Kit
qui detecte les bords de la cible et la redresse de face automatiquement
(mode base = sans filtre couleur, pour conserver les couleurs reelles).

- nouveau service DocumentScannerService (scanTarget)
- capture_screen branche sur le scanner mlkit, reglages galerie 1280/q75 conserves
- AndroidManifest: meta-data com.google.mlkit.vision.DEPENDENCIES=docscanner
