Improve ML dependency installation script for robust deployment

Update deployment script to correctly activate virtual environment, install Cython and numpy as build dependencies before eif, and ensure sequential installation for the ML hybrid detector.

 **Dipendenze nuove**:

-- `xgboost==2.0.3` - Gradient Boosting per ensemble classifier
-- `eif==2.0.2` - Extended Isolation Forest
-- `joblib==1.3.2` - Model persistence

+- `eif==2.0.2` - Extended Isolation Forest (Step 3)
+- `joblib==1.3.2` - Model persistence (Step 3)
 
-**Perché lo script separato?**
-`eif` richiede Cython per compilare il codice durante l'installazione. Lo script installa Cython PRIMA, poi le altre dipendenze.
+**Perché lo script in 3 fasi?**
+1. `eif` si compila da source e richiede **Cython** durante setup.py
+2. `eif` setup.py fa `import numpy` → richiede **numpy pre-installato**
+3. Lo script attiva **venv** e installa sequenzialmente: Cython → verifica numpy → eif
