feat: add Nostr Wallet Connect (NWC) integration (#131)

* feat: add Nostr Wallet Connect (NWC) integration

Add NWC (NIP-47) support to connect Lightning wallets:
- Add NWCConnection type and state management
- Implement custom NWC client service for wallet communication
- Create ConnectWalletDialog for entering connection strings
- Add wallet button to user menu showing balance
- Display wallet info (balance, alias) in user menu dropdown
- Support get_info, get_balance, pay_invoice, make_invoice commands
- Persist wallet connection to localStorage
- Install applesauce-wallet (for future NIP-60 support)

Note: Current implementation uses custom NWC client. Can optionally
switch to @getalby/sdk for official Alby SDK support.

* refactor: use applesauce-wallet-connect and move wallet to header

Replace custom NWC client implementation with applesauce-wallet-connect:
- Install applesauce-wallet-connect for official NIP-47 support
- Create nwc.ts service wrapper for WalletConnect singleton
- Update NWCConnection type to match WalletConnectURI interface
- Use service/relays/secret properties instead of custom names

Move wallet display from user menu to header:
- Create standalone WalletButton component
- Add WalletButton to header next to UserMenu
- Remove wallet UI from user menu dropdown
- Show balance in header with yellow zap icon
- Clicking wallet button opens connect dialog

This provides better UX with wallet status visible in header
and uses the official applesauce implementation for reliability.

* feat: improve wallet button UX and add detailed info dialog

UI improvements:
- Remove border and padding from wallet button (use ghost variant)
- Remove "sats" suffix from balance display (show just the number)
- Change click behavior to show detailed wallet info dialog

Wallet info dialog:
- Show balance prominently without suffix
- Display wallet alias if available
- Show lightning address (lud16) if present
- List all supported NWC methods as badges
- Display connected relay URLs
- Add disconnect button with confirmation toast

This provides a cleaner header appearance and better wallet
management with all details accessible in one place.

* refactor: move wallet functionality to user menu

Move wallet connection and info from separate header button into
the user menu dropdown for better organization.

Changes:
- Remove standalone WalletButton component
- Add wallet section to user menu dropdown
- Show "Connect Wallet" option when no wallet is connected
- Display wallet balance and alias when connected
- Clicking wallet info opens detailed dialog with:
  - Balance (without suffix)
  - Wallet name/alias
  - Lightning address (lud16)
  - Supported NWC methods
  - Connected relay URLs
  - Disconnect button

This consolidates all user-related settings (account, relays,
blossom servers, wallet) in one consistent location.

* feat: improve wallet UX with profile-based naming and better layout

UX improvements:
- Use service pubkey username/profile as wallet name instead of alias
- Remove format hint text from connection string input
- Move wallet to single row directly below user name (remove label)
- Use RelayLink component for relay URLs in wallet info dialog
- Show wallet name from service profile with fallback to alias/pubkey

This provides better integration with Nostr profiles and a cleaner,
more compact menu layout. The wallet service provider's identity is
now shown using their actual Nostr profile name.

* feat: add persistent wallet service with auto-updating balance

Implement comprehensive NWC wallet management architecture:

**Service Layer** (`src/services/nwc.ts`):
- Maintain singleton WalletConnect instance across app lifetime
- Poll balance every 30 seconds for automatic updates
- Subscribe to NIP-47 notifications (kind 23197) for real-time updates
- Expose RxJS observable (balance$) for reactive balance changes
- Restore wallet from saved connection on app startup
- Proper cleanup on disconnect

**Hook Layer** (`src/hooks/useWallet.ts`):
- useWallet() hook exposes wallet throughout the app
- Provides methods: payInvoice, makeInvoice, getBalance, etc.
- Auto-syncs balance updates with Jotai state
- Handles wallet restoration on mount
- Type-safe wrapper around WalletConnect API

**UI Updates**:
- Add refresh button to wallet info dialog
- Auto-update balance display when transactions occur
- Proper cleanup on wallet disconnect

**Architecture**:
```
User Action → useWallet() → NWC Service → WalletConnect
                ↓                ↓
         Update State ← balance$ observable ← Polling/Notifications
```

This enables:
- Real-time balance updates when paying/receiving
- Easy wallet access: `const { payInvoice, balance } = useWallet()`
- Persistent connection across page reloads
- Automatic polling as fallback for notifications

* refactor: make NWC fully reactive with notifications and graceful balance handling

Changes:
- Remove polling mechanism in favor of pure reactive notifications$ observable
- Subscribe to wallet.notifications$ for real-time balance updates
- Make balance display conditional (only show if available)
- Fix TypeScript errors (notification.type access, unused variable)
- Remove Jotai callback mechanism for balance updates
- Use use$() directly for reactive balance subscription
- Update comments to reflect reactive architecture (no polling)

The wallet now updates balance automatically when payments are sent/received
via NIP-47 notifications, with no polling overhead.

* feat: improve wallet UX with profile-based naming and better layout

Improvements to NWC wallet UI:
- Add separator between user info and wallet section in menu
- Show wallet icon instead of zap icon for better clarity
- Display connection status indicator (green/red dot) in both menu and dialog
- Make wallet service username clickable in wallet info dialog to open profile
- Use wallet relays as hints when fetching service profile for better resolution
- Enhanced useProfile hook to accept optional relay hints parameter

The wallet now properly resolves service profiles using the NWC relay
and shows visual connection status at a glance.

* fix: remove toast descriptions for better contrast
