fix(db): declare onDelete on required FKs that had none

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.
