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
