refactor: Remove manual authentication button, improve auto-flow

**Motivations :**
- Remove unnecessary 'Authenticate with Browser' button since authentication is automatic
- Simplify UI by removing manual interaction requirement
- Add better logging for relay connection debugging

**Modifications :**
- Removed mainPairingButton from home.html template
- Simplified setupMainPairing() to not handle button events
- Cleaned up handleMainPairing() to remove button state management
- Added relay connection success logging in router.ts

**Pages affectées :**
- src/pages/home/home.html - Removed authentication button
- src/pages/home/home.ts - Simplified authentication flow
- src/router.ts - Added relay connection logging
