migrate: flag the account instead of renaming it

Renaming to <name>v2 was a hack for freeing the username, and v3/v4/v9
fallbacks made it worse. The page now sweeps the balance and sets the
new `migrated` flag: the registrar takes over receiving for the name
while the old account keeps working here, unchanged.
