core: names are the device's, so drop the per-profile account

A name's profile is the record it resolves to, not the key that owns it, so
the account level was carrying a mapping nothing needs. It was also the only
source of the profile to account ambiguity after a restore, of /_wallet
bind, and of the index gap and the refusal that told a visible profile an
account was held by one it cannot see. All of it goes.

Names sit in account 0 from index 1. Index 0 is left unused so neither the
names nor the profile accounts, which start at 1, claim the origin of both
dimensions. users gains no columns at all now, so the migration is one
CREATE TABLE.
