Issue 4.1: Connect Freighter Wallet

[soomtochukwu]

Description:
Users must be able to sign transactions and prove their identity on Stellar. The standard way is using the Freighter browser extension.

Requirements:

• Add @stellar/freighter-api to frontend/package.json.
• Create a reusable "Connect Wallet" button component in the Dashboard header.
• Detect if Freighter is installed; prompt the user to install it if missing.
• Save the user's public key in React state or context.

Acceptance Criteria:

• Clicking the button triggers the Freighter popup.
• Upon approval, the UI updates to show the truncated public key (e.g., GABC...1234).
• Missing extension gracefully shows a "Please install Freighter" modal.
