Add wallet connection status badge component

[Just-Bamford]

Category: Feature - Frontend
Difficulty: Easy

Problem:
No reusable component to display wallet connection state. Applications must build their own UI for showing connected/disconnected status.

Solution:
Create a reusable WalletStatusBadge component that displays the current wallet connection state with visual feedback.

Requirements:

• Show connected/disconnected status
• Display wallet adapter name (Freighter, Ledger, etc.)
• Show account address truncated
• Support loading state during connection
• Accessible with ARIA labels

Acceptance Criteria:

• Component renders correctly in all states
• Unit tests cover all states
• Storybook story added
• Works with dark/light modes
• 80%+ test coverage

Note for Contributors: This is a UI component. Keep it simple and follow existing component patterns in sorokit-ui.
