Make wallet configuration optional and add new event kinds

  - Make REACT_APP_WALLET_BASE_URL optional in config.ts
  - Add isWalletEnabled flag to detect wallet availability
  - Update SendButton and TopUpBalanceButton to show helpful messages when wallet not configured
  - Add support for kind 1060 (Double Ratchet DM - NIP-117), kind 1063 (File Metadata - NIP-94), and kind 30078 (Application-specific Data
  - NIP-78)
  - Simplify icon upload to use new backend API instead of client-side Blossom upload
  - Update .env.production to show wallet URL as optional (empty by default)
  - Update README documentation to reflect optional wallet configuration
  - Users can now deploy panel without wallet service and get clear guidance on enabling wallet features

-- ✅ **Explicit Service URLs Required** - Wallet and relay URLs must be configured in environment variables
+- ✅ **Relay URL Required** - REACT_APP_OWN_RELAY_URL must be configured for profile fetching

 - ✅ **Panel Routing Auto-Detection** - Panel paths (REACT_APP_BASENAME/PUBLIC_URL) can be auto-detected
 - ✅ **Build-Time Configuration** - Service URLs are baked into the JavaScript bundle during build
 - ✅ **Simple Deployment** - No reverse proxy needed for basic functionality

 ### Service URLs
-**🎯 Explicit Configuration Required**: Service URLs must be explicitly configured:
-- **Wallet Service**: `REACT_APP_WALLET_BASE_URL=http://localhost:9003` (required)
-- **Relay WebSocket**: `REACT_APP_OWN_RELAY_URL=ws://localhost:9001` (required)

+- **Relay WebSocket**: `REACT_APP_OWN_RELAY_URL=ws://localhost:9001` (required for profile fetching)
 - **Panel API**: Auto-detected from current origin (no configuration needed)
 
+**Note**: When wallet URL is not configured, send/receive buttons will show a helpful message about rebuilding with wallet configuration.

 **Manual Override** (development only):
 - **REACT_APP_BASE_URL**: Panel API endpoint (dev mode only)
 - **REACT_APP_WALLET_BASE_URL**: Wallet service endpoint (dev mode only)
