fix(profile): hide '_@' prefix on NIP-05 in profile header

Per NIP-05, when the local part is '_', the address should display as
just the domain. The profile header was calling Nip05Id.toValue() which
always returns 'name@domain', producing '_@houseofeff.com' on screen.
Match the pattern already used in NIP05VerificationDisplay,
AwardBadgeScreen, RelayManagementScreen, and NewCommunityScreen.
