Three faults in the same migration:
- up()'s removal loop was driven by operatorUserIds() (model_has_roles
WHERE model_type=User) via the $carried array — but carryAcross()
repoints model_has_roles to Operator for every operator before a
single users row is deleted. A run that stops partway (the
customer-conflict abort, or a dropped connection on real MariaDB,
which this file deliberately runs without a transaction) leaves that
worklist empty on the next attempt, so `migrate` records the
migration as applied while every leftover users row still grants a
live portal login on the operator's own password. Now driven by
`operators` joined to `users` on email: that finds every
carried-but-not-yet-deleted row regardless of which run carried it.
- operatorUserIds() had no ORDER BY. carryAcross() remaps four owned
columns in place, keyed on the old users.id, while operators.id hands
out new values in the same order the list is walked — unordered, a
later operator's freshly assigned id can equal an earlier operator's
still-unprocessed users.id, and the second remap catches a row the
first one already rewrote. One operator ends up silently owning
another operator's VPN peer. Added ->orderBy('model_id').
- down() restored model_has_roles but not model_has_permissions, so an
operator holding a direct (not role-granted) permission lost it on
rollback. Mirrored the same move carryAcross() does forward.
Also removes seed_roles_and_permissions' now-stale
User::OPERATOR_ROLES/hasAnyRole()/assignRole() bootstrap loop — all
three gone from User per this branch's own work — which only a deep
rollback (down() of the move migration recreates is_admin users) would
ever have reached, but would fatal when it did.
