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)
