LNbits 1.4 changed check_super_user to return Account (no wallets)
instead of User (with wallets). This broke the template rendering
because LNbits.map.user() requires the wallets property.
Switch to check_user_exists (returns User with wallets) and manually
check user.super_user for access control. This follows the same
pattern used by LNbits core admin pages.
