**Motivations :**
- Fix createProcess waiting when relay is already ready
- Prevent creating new promise when handshake already received

**Modifications :**
- Check if relay already has spAddress before creating new promise
- Return resolved promise immediately if relay is ready
- Prevents infinite waiting in createProcess

**Pages affectées :**
- src/services/service.ts - Enhanced relay ready logic
