feat: FASE 5b/6.1+6.2 - SPC Backend + Dashboard Metrologist (Plotly.js)

Aggiunge servizio SPC con calcoli Cp/Cpk/Pp/Ppk, carta di controllo (UCL/LCL),
istogramma con curva normale. Router FastAPI con 5 endpoint statistics, blueprint
Flask con proxy AJAX, dashboard interattiva Alpine.js + Plotly.js con filtri per
ricetta/subtask/date, riepilogo pass/fail, gauge Cpk e i18n IT/EN completo.
