fix: Create relay ready promise at connection start

**Motivations :**
- Fix timing issue where handshake resolves promise before createProcess waits for it
- Ensure promise exists when handshake arrives

**Modifications :**
- Create relay ready promise immediately when starting connections
- Prevents race condition between handshake and createProcess

**Pages affectées :**
- src/services/service.ts - Fixed promise timing in connectAllRelays
