// a) Insert financial_entity with NULL owner_id (breaks circular dependency temporarily)
// b) Insert business row (now has valid financial_entity reference)
// c) Update financial_entity to set owner_id = self (closes the circle)

// This 3-step process is necessary because PostgreSQL doesn't support DEFERRABLE
// constraints on our foreign keys, and we need both tables to reference each other.
