feat: Display 4 words immediately after credentials generation

**Motivations :**
- Show 4 words to user as soon as credentials are generated
- Improve user experience by not waiting for full pairing process

**Modifications :**
- Moved generateWordsDisplay call to execute right after address is obtained
- Removed duplicate call at end of pairing process
- Users now see words immediately after WebAuthn authentication

**Pages affectées :**
- src/utils/sp-address.utils.ts - Early 4 words display
