Initial commit: aplicatie de cantarire si etichetare

Aplicatie Flask + SQLite pentru productie alimentara: cantarirea
componentelor unui produs finit si tiparirea etichetei prin QZ Tray.

- produse finite (retete) formate din componente cantarite
- designer vizual de etichete (mm/px, zona sigura, campuri variabile,
  cod QR cu continut din mai multe bucati)
- legare produs finit -> sablon de eticheta
- navigare pe doua taburi: Cantarire / Setari
- administrare: componente, produse finite, sabloane, campuri, istoric
- backup, resetare baza de date, checklist de pregatire, /healthz
- CLI de administrare si serviciu systemd pentru productie
- vendor/syncpulse-scale-bridge (GPL-3.0-or-later) pentru citirea cantarului
