Phase 3 of the quote-to-close funnel spec: client.owner_id added additively
(SCHEMA + PRAGMA-guarded migrate) so a bare lead is routable to an employee;
setClientOwner repo fn (validates active employee, audits set_owner in-txn);
PATCH /clients/:id/owner gated inline to owner/manager; shared ownerScope role
gate (staff forced to self, widening ignored) for later phases; ClientDetail
gains an owner/manager-only Account owner dropdown fed by GET /employees.
