fix: Prevent handshake processing loop and auto-trigger WebAuthn

**Motivations :**
- Fix infinite loop of 'process.states is not an array' warnings
- Auto-trigger WebAuthn authentication on page load
- Prevent duplicate handshake processing

**Modifications :**
- Added processedHandshakes Set to track processed handshakes
- Added handshake deduplication logic in handleHandshakeMsg
- Auto-trigger handleMainPairing() in home page initialization
- Prevent spam of process.states warnings

**Pages affectées :**
- src/services/service.ts - Added handshake deduplication
- src/pages/home/home.ts - Auto-trigger WebAuthn on init
