Add offline and degraded-network states

[Naomi-Gift]

Problem

The app does not detect offline status or degraded network conditions. Users may attempt wallet or verification actions while network calls cannot complete.

Suggested fix

Use browser online/offline events and request failures to show a global network status banner.

Acceptance criteria

• Offline state is visible across the app.
• Network-dependent actions are disabled or clearly warned while offline.
• The app recovers when connection returns.
