feat: show correct connection type on debug page

Updated debug page to display the actual account type:
- Browser Extension (type: 'extension')
- Bunker Connection (type: 'nostr-connect')
- Account Connection (fallback)

Changes:
- Section title now reflects active account type
- Connection status message updated accordingly
- No longer always shows 'Bunker Connection' regardless of type

Makes it clear to users which authentication method they're using.
