feat: FASE 7 - Polish & Testing (security, i18n, test suite, docs)

Browse Source 
Security hardening: CORS lockdown, rate limiting middleware con sliding
window e eviction IP stale, security headers (CSP, HSTS, X-Frame-Options),
session cookie hardening, filename sanitization upload.

i18n completion: internazionalizzati barcode.js e csv-export.js con bridge
window.BARCODE_I18N/CSV_I18N, aggiornati .po IT/EN con 27 nuove stringhe.

Tablet UX: touch target 44px per dispositivi coarse pointer.

Test suite: 101 test totali (76 server + 25 client), copertura completa
di tutti i router API, autenticazione, ruoli, CRUD, SPC, file upload,
security integration. Infrastruttura SQLite async in-memory con fixtures.

Fix critici: MissingGreenlet in recipe_service (selectinload eager),
route ordering tasks.py, auth_service bcrypt diretto, Measurement.id
Integer per SQLite.

Documentazione: API.md (riferimento completo 40+ endpoint),
DEPLOYMENT.md (guida produzione con Docker/Nginx/SSL),
USER_GUIDE.md (manuale utente per ruolo).
