feat(apk): scanner le QR du poste depuis l'app (ZXing.Delphi, Apache 2.0)

Le scanner du systeme demandait avec quoi ouvrir le lien. L'app ouvre la camera arriere, decode une image sur quatre et remplit URL + jeton des qu'un lien pmserver://sync est lu. Rien n'est enregistre avant Save. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
