The one-time ClientsTable migration builds client records from each
inbound's settings with a plain Create, and gorm's default:true on
ClientRecord.Enable drops an explicit false from that insert. Every
client an operator had disabled before v3.1.0 was therefore stored
enabled on an in-place upgrade or a restored backup, and Xray, which now
reads that column, let the customer back in.
The seeder restates enable=false after Create, as the service paths do
since #6478, and a legacy client whose settings carry no switch stays
enabled, as releases before 3.1.0 served it.
