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.
