Eight required (nullable:false) FKs had no referential action. Set per the codebase's existing pattern: CASCADE for owned relations (doctor_insurances, doctor_secretaries), RESTRICT for owner/reference FKs (Doctor/Clinic.user_id, invited_by_id, subscription plan/period). Only the two CASCADE FKs need DDL — RESTRICT is the MySQL default.
