Display existing processes in status field

**Motivations :**
- User wants to see each retrieved process displayed as a message in the status field
- Need to show process information after authentication or initialization

**Modifications :**
- Added displayExistingProcesses() function to fetch and display processes
- Modified handleMainPairing() to call displayExistingProcesses() after authentication
- Modified initHomePage() to display processes even if authentication fails
- Each process shows: ID (truncated), states count, members count, last update
- Processes displayed in scrollable container with styled cards
