+/**
+ * `freight.companies.region` was free text until region became a closed set
+ * (see ETHIOPIAN_REGIONS in @edr/types). This normalizes the rows written under
+ * the old rules so they satisfy the new dropdown.
+ *
+ * Two classes of bad data exist, handled differently:
+ *
+ *  - Unambiguous spelling/case drift ("Addis ababa", "oromoia") — rewritten to
+ *    the canonical spelling.
+ *  - Values that are not regions at all ("Arba Minch", a city), and rows whose
+ *    region contradicts their own zone/woreda — set to NULL. These are NOT
+ *    guessed at: inferring "Gurage/Meskan" means Central Ethiopia would silently
+ *    overwrite what the customer actually submitted. NULL surfaces the gap and
+ *    the required dropdown forces a deliberate pick on next edit.
