Add WalletConnect support

[Lakes41]

The wallet hook currently includes a TODO for production wallet integrations. Add WalletConnect support so users can connect their real wallet instead of manually entering an address.

Suggested tasks

• Add WalletConnect integration
• Add a “Connect Wallet” button to the profile screen
• Store the connected wallet address in the wallet store
• Handle connection errors and rejected requests
• Keep manual address entry available for MVP testing if needed

Acceptance criteria

• Users can connect through WalletConnect
• Connected wallet address appears on the profile screen
• Failed or cancelled wallet connections show a useful error

Taking this. Adding WalletConnect support — will integrate with the existing wallet connection flow in guildpass-mobile, add WC provider, and wire it to the connect button.
