Remove unnecessary NDK initialization and external relay connections

- Remove NDK initialization since login uses window.nostr directly
- Remove external relay URLs (relay.damus.io, relay.snort.social, etc.)
- Profile API uses panel API instead of direct relay connections
- Eliminates WebSocket connection errors to external relays
- Simplifies app startup and reduces external dependencies
- All Nostr operations now go through panel API or browser extension
