feat: add comprehensive NWC wallet viewer with dynamic UI

Implements a full-featured Lightning wallet interface using Nostr Wallet
Connect (NWC/NIP-47) with method-based UI that adapts to wallet capabilities.

**New Features:**
- WalletViewer component with tabbed interface (Overview, Send, Receive, Transactions)
- Real-time balance display with manual refresh
- Send Lightning payments via BOLT11 invoices
- Generate invoices with QR codes for receiving payments
- Transaction history viewer (when supported by wallet)
- Wallet info and capabilities display
- Enhanced useWallet hook with additional NWC methods

**Enhanced Methods:**
- listTransactions() - View recent payment history
- lookupInvoice() - Check invoice status by payment hash
- payKeysend() - Direct keysend payments to node pubkeys

**UI Features:**
- Dynamic tabs based on wallet capabilities
- QR code generation for invoices
- Copy-to-clipboard for invoices
- Error handling with user-friendly messages
- Loading states for async operations
- Empty states for no wallet connection

**Command:**
- New `wallet` command to open the wallet viewer

**Technical Details:**
- Integrates with existing NWC service singleton
- Uses reactive balance$ observable for auto-updates
- Proper TypeScript types aligned with applesauce-wallet-connect
- Follows Grimoire patterns for window system integration
- Lazy-loaded component for optimal bundle size

All tests passing. Build verified.
