feat: FASE 0 - Setup progetto TieMeasureFlow

Struttura monorepo completa con server FastAPI e client Flask:
- Server: FastAPI + SQLAlchemy 2.0 async + Alembic migrations
- Client: Flask + blueprints (auth, measure, maker, statistics)
- Database: docker-compose MySQL 8.0 + Alembic async config
- Config: pydantic-settings, TailwindCSS, Flask-Babel i18n
- Piano implementazione completo (18 sezioni, 1600 righe)

+# TieMeasureFlow - Istruzioni Progetto
+
+## Panoramica
+TieMeasureFlow by Tielogic - Sistema di gestione task per misurazioni con calibro manuale.
+Monorepo con server FastAPI (backend API) e client Flask (frontend tablet).
+
+## Stack
+- **Server**: FastAPI + SQLAlchemy 2.0 async + asyncmy + MySQL 8.0
+- **Client**: Flask 3.0 + Jinja2 + htmx 2.0 + Alpine.js 3.x + TailwindCSS 3.x
+- **Grafici**: Plotly.js (browser) + Kaleido (server export SVG)
+- **PDF**: WeasyPrint (HTML → PDF), PDF.js (rendering browser)
+- **Annotazioni**: Fabric.js 6.x (editor Maker), Canvas overlay (display MeasurementTec)
+- **i18n**: Flask-Babel (server) + alpinejs-i18n (client), lingue IT/EN
+- **Auth**: API Key nell'header X-API-Key
+

+```
+
+## Convenzioni Codice
+- Python 3.11+, type hints ovunque
+- async/await per tutte le operazioni DB (server)
+- Pydantic v2 per validazione I/O API
+- Nomi variabili e commenti in inglese, UI strings in IT/EN via i18n
+- File imports ordinati: stdlib, third-party, local
+- Nessun import wildcard (from x import *)
+
+## Database
+- MySQL 8.0 con charset utf8mb4
+- SQLAlchemy 2.0 async con asyncmy driver
+- Alembic per migrations
+- Tabelle: users, recipes, recipe_versions, recipe_tasks, recipe_subtasks, measurements, access_logs, system_settings, recipe_version_audit
+
+## Ruoli Utente
+- **Maker**: crea/modifica ricette
+- **MeasurementTec**: esegue misurazioni
+- **Metrologist**: visualizza statistiche SPC
+- Ruoli combinabili (JSON array), flag `is_admin` separato
+
+## Pattern Importanti
+- **Recipe Versioning**: copy-on-write immutabile. Modifiche creano nuova versione, misure restano legate a versione originale
+- **Pass/Fail**: calcolato da tolleranze UTL/UWL/LWL/LTL su ogni subtask
+- **File Storage**: uploads/{images,pdfs,logos,reports}/{recipe_id}/{version_id}/
+
+## Comandi
+- Server: `cd server && uvicorn main:app --reload --host 0.0.0.0 --port 8000`
+- Client: `cd client && flask run --host 0.0.0.0 --port 5000`
+- Migrations: `cd server && alembic upgrade head`
+- TailwindCSS: `cd client && npx tailwindcss -i static/css/input.css -o static/css/tailwind.css --watch`
+
+## Brand
+- Colore primario: #2563EB (blu industriale)
+- Colore secondario: #64748B (grigio acciaio)
+- Font UI: Inter
+- Font numeri: JetBrains Mono
